Useful Computer Motherboard Installation Instructions

noreply@blogger.com (GM Qazi) — Fri, 08 Apr 2011 10:36:00 +0000

Computer's motherboard takes steps like the central anxious system, linking with each other all other systems of the computer and giving them a central location to communicate with each other. The motherboard is pillar of the computer like the hard drive, DVD drive, RAM and CPU would be not capable to function together. If you need to install a motherboard in your computer, you can do so, but be alert that this is a procedure that should only be undertaken if you have some reasonable experience in this field of computer. Now read the following step by step suggestions and tips regarding install of Computer Motherboard.

1. Rising the Motherboard onto the Casing.

WARNING: Handle motherboards gently by the edges. Some of the component leads under the board have sharp edges and may cause serious injury. To prevent electrostatic discharge damage to the components on your motherboard, do not remove the motherboard from the static-shielded bag until you have discharged any static electricity from your body by touching any unpainted surface on the case of your computer.

• Most computer cases have a base with many mounting holes that allow the motherboards to be securely attached to the case and prevent the back of the motherboard touching the metal case and short circuits.

• There are two ways to attach the mainboard to the base: (1) with plastic spacers or (2) with metal bolts .

• In principle, the best way to attach a motherboard is with bolts and only if you are unable to use a bolt should you attach the motherboard with spacers. Some cases come with a combination of spacers and bolts. Use bolts whenever you can.

• Newer and better computer cases come with bolts built into the base, saving you the time to screw the bolts on.

• Most detached motherboard base bolts come in either copper or stainless steel. Two sizes of screws are used, depending on the case manufacturer. Choose the screw size carefully. Do not use case screws for mounting motherboards or any drives. Case screws are designed to "lock" in the sheet metal, which may damage the female screw holes on the bolts or drives.

• Take a careful look at the mainboard and you will see many mounting holes. Line these holes up with the mounting screw holes or slots on the base. For motherboard holes that line up screw holes on the base, you can attach them with bolts. For bolt positions, do not tighten the screws until all the screws are in. Sometimes, you may need to move the motherboard slightly to make the screw holes fit.

• If the motherboard holes line up with slots, attach these positions with spacers. Take the tip of the spacers and insert it into the slots. After doing this to all the slots, you can slide the mainboard into position aligned with the slots.

• If the motherboard has mounting holes, but they don't line up with the holes on the base and there are no slots to attach the spacers, the spacer would be too tall. Just cut the "feet" on the spacers with a wire cutter. (The spacers may be very hard, so be careful when cutting). In this way you can still attach the motherboard to the base without worrying about short circuits.

2. Standard External Connectors.

• Several cables and plugs from the inside of the case must be connected to the motherboard. These cables and plugs are usually connected manually and one-by-one to connectors on the motherboard. You need to pay attention to any connection orientation for the cables and plugs. If any, notice the position of the first pins of the connectors on the motherboard, which are often marked.

• The actual position and marking of the connectors on the motherboard vary greatly from brand to brand and from model to model. Read your motherboard manual carefully before any installation. Here is a list of most frequently used connections and their purposes:

o System speaker (often 4-pin plug), for system sound.

o Hardware reset connector (often 2 pin plug), for resetting/rebooting the computer.

o Keylock and power LED connector (4 or 5-pin plug), for indicating computer on and off.

o HDD LED connector (often 2-pin plug), for indicating the usage of hard disc drives.

o Power connectors for case or microprocessor fan, supplying DC power to fans.

o Power switch (often 2-pin plug), for turning the computer on and off.

o DC power input connector (One 20-pin plug for ATX for 3.3V, +5, -5, +12, and -12V DC voltages; two 6-pin plugs for AT for +5, -5, +12 and -12V DC voltages), supplying DC power to the motherboard.

o For ATX motherboards, serial and parallel ports are built-in on the motherboard. For AT motherboards, you must also connect these ports to the corresponding connectors on the motherboards. Watch for the polarity of the plugs for the ports. Align the colored edge of the ribbon cables to Pin 1 on the connectors.

o For ATX motherboards, PS2 mouse connectors are integrated into the motherboard. For AT motherboards you must attach a serial mouse to one of the serial port. Or you may have a PS2 mouse connector on the motherboard to use a PS2 mouse on an AT motherboard.

o Some ATX motherboards come with ATX form factor connectors (8 pins).

o Motherboards with integrated audio and/or video will come with special cables and plugs for these onboard devices. Consult your motherboard manual for details.

3. Jumper Settings

• Jumper switches on the motherboard are often used to configure various hardware options. To avoid losing jumper caps, attach the removed jumper caps to one of the jumper pins. Putting a jumper cap on two jumper pins connects them.

• You must change jumper settings if you change the microprocessor speed and type. Sometimes you need to change the jumper settings if you change the memory type.

• Most jumper positions and pin assignment are marked on the motherboards. The actual positions and meaning of the jumpers vary greatly among motherboards. Read your motherboard manual carefully before any installation. Here is a list of most of used jumpers:

o CPU type selection
o CPU microprocessor external clock selection
o CPU microprocessor internal clock speed selection
o CPU microprocessor core voltage selection
o PCI BUS clock selection
o DIMM voltage selection (3.3V vs. 5V)
o CMOS RAM discharge selection

4. Jumperless motherboards

Jumperless motherboards, most often used by QDI, ABIT and Intel, use software to configure the above hardware options, instead of hardware jumpers. The advantage of this technology is the convenience to change the configuration without opening the computer or know the jumper positions.

5. Installing microprocessors

The mounting mechanism for CPUs vary from one type to the other. Consult your motherboard manual for mounting these microprocessors. These are the main types of microprocessors that are still in the market and are not interchangeable:

• Socket 478, for Pentium 4 and newer Celeron
• Socket 423, for older Pentium 4
• Socket A / 462, for AMD Athlon Thunderbird, Duron, and XP
• Socket 603/604, for Intel Xeon
• Socket 940, for AMD Opteron
• Socket 7, for classic Pentium and Pentium MMX, AMD K6, and Cyrix microprocessors
• Super Socket 7, for AMD K6-2 and K6-3 microprocessors
• Socket 370, for Intel Celeron microprocessors and Pentium III
• Slot 1, for Intel Pentium II and III microprocessors
• Slot A, for AMD Athlon microprocessors

6. BIOS setup

• Warning: Changing motherboards from one brand to another sometimes requires reformatting the hard drive and reloading the operating system. Choose your motherboard and read the motherboard manual thoroughly before upgrading.

• BIOS is a program located on a Read-Only Memory (ROM) chip on the motherboard. This program will not be lost when you turn the main power to your computer off. This program is also sometimes referred to as the boot program. It is the only channel for the hardware circuit to communicate with the operating system. Its main function is to manage the setup of the basic parameters for motherboard and interface cards. These parameters include simple ones such as time, date, hard disk drive, as well as more complex ones such as hardware synchronization, and device operating mode.

• WARNING: Do not change any parameters inside the BIOS unless you know what you are doing! The parameters inside the BIOS are used to set up the hardware synchronization or the device operating mode. If these parameters are incorrect, they may produce error, the computer may crash, and sometimes you may even not be able to boot the computer after it crashes. We suggest you not to change the parameters inside the BIOS unless you are familiar with them.

• When you start your computer, the computer is first controlled by the BIOS program. The BIOS runs an auto-diagnostic procedure for all the necessary hardware, configures the parameters for the hardware synchronization, and detects all the hardware. After it completes these tasks, BIOS gives up the control of the computer to the program of the next level, which is the operating system.

• Since the BIOS is the only channel for hardware and software to communicate, it will be the key factor to system stability and optimal performance. You lose your customized BIOS setting if the CMOS battery on your motherboard is removed or fails. Your BIOS goes back to its original manufacturer default if that happens.

• How to set up BIOS is beyond the scope of this guideline. We may add a section just for that. Please always consult your motherboard's manual. Here are list of most often used functions you can configure with BIOS:

o Standard CMOS Setup Date, hour, HDD operating mode (Normal, LBA, Large), video card, and floppy drive.

o BIOS Features Setup These are common features: Virus warning. CPU level 1 cache. CPU level 2 cache. CPU level 2 cache ECC checking. Quick power-on self-test. Boot sequence. Swap floppy drive. Boot-up floppy seek. Boot-up Numeric Keypad lock status. IDE HDD block mode. Security options.

o Chipset Features Setup This menu is used to modify the contents of the buffers in the chipset on the motherboard. Since the parameters of the buffers are closely related to hardware, the motherboard may become unstable or you may not be able to boot up if the setup is not correct. If you don't know the hardware well, use default values.

o Power Management Setup The difference between Green PCs and traditional computers is that Green PCs have a power management feature. With this feature when the computer is powered on but inactive, the power consumption is reduced in order to save energy. When the computer operates normally, it is in Normal mode. In this mode, the Power Management Program will monitor the access to video, parallel ports, serial ports, and drives and the operating status of the keyboard, mouse and other devices. These are referred to as Power Management Events. In cases when none of these events occur, the system enters the Power Saving Mode. When one of these events occurs, the system immediately returns to normal mode and operates at its maximum speed.

o PCI & Onboard I/O Setup In this menu, you can change the INT# and IRQ of the PCI bus and the onboard I/O devices, I/O port addresses and other hardware settings.

o Password Setting This option allows you to set a password required to start the system or to access to the BIOS setup.

o IDE Hard Disk Drive (HDD) Auto Detect After you have installed the hard disk in an old system, you had to know the hard drive specifications, such as the number of cylinders, heads, and sectors, and to enter the relevant information into the hard disk information section of BIOS. If the CMOS data were erased and you had forgotten the hard disk specifications, it creates a big program. Nowadays, you can use this option to autodetect the hard disk type and specifications, and the BIOS will automatically detect all the relevant information and place them in the Hard Disk Data section of the Standard CMOS Setup Menu, in order to allow you to use your hard disk.

In view of the above useful Computer Motherboard Installation Instructions you should be keep in mind really very informative and profitable for the filed of Computer Hardware in New Technology.

Top 10 Motherboards for PC look New Technology

noreply@blogger.com (GM Qazi) — Fri, 08 Apr 2011 08:32:00 +0000

In the new Computer Technology look following Top 10 Motherboards are ranked according to site traffic, and are not based on review scores or selection by the PC & Technology Authority team. This list shows which products are receiving the most interest from readers visitors and persons have been using these Motherboards in all over the world these are very useful and consisting on nice technology.

1. Gigabyte GA-EP35C-DS3R, our new favourite all-round board

A great combination of features at an excellent price makes this our new A-List board - suitable for just about everyone.
Price: AUD $145

Different motherboards suit different uses, and no single board will be right for everyone. But we’d recommend the Gigabyte GA-EP35C-DS3R to anyone, because it offers so much for such a good price.

First off, the gimmick. While the other boards here make you choose between DDR2 and DDR3, the Gigabyte will take both. Or, to be precise, it will take either: you can install up to four DDR2 DIMMs or two DDR3 DIMMs, but you can’t use both together. We’d question how useful this really is, but it’s nice to have options.

It’s a liberating board in other ways, too. It provides eight SATA channels, more than any rival. And at the back you’ll find eight USB ports, a generous complement matched only by the far pricier MSI X48 Platinum. There’s also eSATA via a rear bracket.

The BIOS offers Gigabyte’s standard Intelligent Tweaker menu, which gives you freedom to meddle with your PC’s internal clocks, adjust the CPU multiplier, and boost FSB and RAM speeds. It’s nicely accessible, but you can also get at most of these settings from within Windows using the EasyTune applet.

2. Gigabyte's GA-890FXA-UD7 is our new A-List motherboard

Gigabyte's GA-890FXA-UD7 ships with an interchangeable water block and large passive cooler for the north bridge.

Price:AUD $249

The board pairs the SB850 south bridge with several extra chips to extend its feature set. Besides the six SATA 6Gbps ports there are two SATA 3Gbps ports and two eSATA ones.

There are also dual gigabit LAN ports, provided by Realtek controllers and USB 3 supplied by an NEC controller chip.

The board also has Gigabyte's new 3x USB power boost technology, which ups power delivery through USB ports in order to charge power hungry devices like the iPad without issues arising.

It has a full complement of PCI-Express slots in order to run up to four graphics cards. While it has a raft of overclocking features (and core unlocking), it isn't as niche as the ASUS offering, and is much more of an all-round performer.

3. Why Asus' M4A89GTD Pro/USB3 is our latest A-listed motherboard

A great motherboard, at a great price. The Asus M4A89GTD Pro/USB3 motherboard is designed for the next generation of AMD CPUs

Price: AUD $223

Asus' latest Socket AM3 motherboard is based on the new AMD 890GX chipset, which includes a SATA/600 controller plus the new Radeon HD 4290 GPU with support for DirectX 10.1 and dual-stream Blu-ray.

The board offers two USB 3 ports, plus a Core Unlocker switch that enables all usable cores on your CPU, potentially turning your X2 or X3 processor into a true quad-core model.

Meanwhile, Turbo Key II automatically pumps up your processor to its highest stable frequency, and GPU Boost does the same for graphics.

If you want to squeeze every drop of performance from an AMD CPU, the M4A89GTD Pro/USB3 makes it easy - although, arguably, you could buy a cheaper board and invest more in the processor in the first place.

4. MSI P4M890M

Your cheapest MicroATX ticket into Intel's Core 2 world

Price: AUD $110

The MSI P4M890 is a MicroATX motherboard, based around a fairly basic VIA P4M890 chipset, which makes it a perfectly capable board for lower end PCs -- which could potentially be office boxes, media centres or secondary PCs.

is not designed as a high end, performance motherboard -- as its $110 price tag and our test results show. Nonetheless, it still boasts two SATA ports as well as two IDE ports for legacy drives. There’s also a RAID controller, integrated video and gigabit ethernet. There are 4 USB ports at the back of the motherboard, along with two USB headers on the motherboard itself, which can take the total to eight if the case you’re planning on using has provisions for the headers, as no expansion brackets are included with the motherboard. In fact, all that’s included in the box is a single SATA cable, an IDE cable, a molex to SATA power converter and a connector backplane.

There are no options in the BIOS to ramp the RAM speed above 533 MHz, and between this and the performance of the Via chipset itself, we saw the MSI P4M890M take a performance hit of about 12 % across our benchmark suite. Under SuperPi, the MSI board took 2 minutes and 22 seconds to calculate Pi to four million decimal places -- 35 seconds slower than the same X6800 in a motherboard armed with a P965 chipset. Looking at this another way shows the performance of our X6800 lowered to the same level as an AMD FX-62.

On the surface, there are a surprising number of overclocking options included. RAM voltages can be adjusted from 1.8 to 2.4 volts, and the FSB can be theoretically pushed from 200 to 500 MHz. We dropped in our Core2 Duo X6800 and wound up the FSB, where we hit a wall just below the 298MHz mark, which gave us an extra 350 MHz on the CPU. After pulling the CPU multiplier back from 11X to 6X we were able to increase FSB to 303 MHz, at which point the motherboard complained, gave up and reset itself to the defaults.

The onboard VIA Unichrome Pro graphics chip powers a single VGA port. It would have been a nice touch for more display options (such as DVI, HDMI or even S-Video) to be made available through a riser card. Sadly this is lacking, restricting its use as a fully featured out-of-the-box media centre board. If you are planning to use the board as the base for a media centre PC, you’ll probably need to use a separate graphics card to provide a more TV friendly output.

There’s a single PCI-e 16x slot provided for this, however if you use a dual slot graphics card you will cover the only PCI-e 1x slot available, leaving you with two PCI slots for expansion.

Under the current BIOS revision, Kentsfield processors are not supported, nor are Conroe processors with an FSB of 1333MHz. This may change in time, however if you are looking at putting together a system on the cheap, this perfectly adequate -- but by no means stellar -- motherboard should suit most lower end applications very well, and still provide an upgrade path if you install a low end chip to begin with. And of course, it’s so bloody cheap to begin with. Bargain.

5. AMD Phenom II X6 1075T, a functional and affordable six-core CPU

AMD's mid-range six-core CPU is a lot cheaper than Intel's six-core offerings, but does that make it a bargain

Price:AUD $308

The Phenom II X6 1075T is AMD’s latest six-core CPU for the AM3 platform. Frankly, there’s nothing very new about it: picture a Phenom II X6 1090T clocked down to 3.0GHz and you’ve got it precisely.

Still, it’s a capable processor. AMD’s Turbo Core technology boosts the frequency to 3.5GHz when three cores or fewer are in use, giving a lift to everyday tasks when heavy multi-threading isn’t required. It isn't as flexible as Intel’s more granular Turbo Boost system, but it helped the 1075T score a solid 1.93 overall in our benchmarks, running under Windows 7 with 2GB of DDR3-1066 RAM. That sets it roughly on a par with Intel’s quad-core i7-870, for around $37 less.

Yet the X6 1075T is not unequivocally a good value option. Yes, the fact that it’s possible to build a complete six-core workstation for under a thousand is impressive. Go the Intel route and you’ll pay more than that for the CPU alone.

But only certain workloads will benefit from a six-core processor. The cheaper Phenom II X4 970 has only four cores, but at its stock speed of 3.5GHz it beat the 1075T in every one of our tests — save for the highly multi-threaded 3ds Max benchmark, where the six-core CPU shaved 8% off the X4’s completion time.

Even if you do need a six core processor, for tasks such as 3D rendering, the top-of-the-range X6 1090T is arguably a better buy. While the X6 1075T is locked at 3.0GHz, its bigger brother is a Black Edition which you're free to clock up to 4GHz and beyond. Even with a regular cooler, this should give a significant performance boost that's well worth the $21or so price difference.

All of which makes the 1075T an attractive option only if you’re extremely averse to tinkering in the BIOS — or if you specifically need six core-power on a very limited budget.

6. Gigabyte EX58-UD5, as future proof as a motherboard gets

A high-quality Core i7 motherboard with great expansion potential and premium features.

Price: AUD $468

Gigabyte currently holds our A-List crown in both the LGA 775 and Socket AM2+ motherboard categories, so our hopes were high for its first board based on the Core i7’s LGA 1336 design.

It’s tough to make a splash in this market, though: Core i7 only works with Intel’s X58 chipset, so all Core i7 boards have a similar basic design, including three-channel RAM and a high-speed QPI bus.

The Gigabyte does have some great strengths. It boasts 40 PCI Express lanes – eight more than the Asus P6T Deluxe – so you can use its three full-length slots in a 16/16/8 configuration.

With support for both SLI and CrossFireX, this gives immense headroom for high-end gamers.

The EX58-UD5 also supports 4GB modules, so you can install 24GB of RAM across its six slots, running at frequencies up to DDR3-2000 and beyond. Its ten SATA ports and 12 USB connectors are generous, too.

One unusual trick is the ability to team the EX58-UD5’s two Gigabit Ethernet ports into one 2Gb connection: a neat idea, but most of us have difficulty saturating a 1Gb link, and you need another 2Gb device to use it.

Of more practical use is the dual-BIOS system, which can restore your BIOS from a backup; a potential life-saver.

We also liked the LED readout mounted on the board to help you troubleshoot hardware problems, although it’s a shame it uses cryptic hex codes instead of text.

The EX58-UD5’s final claim to greatness is its double-thickness conductive copper layers, which are supposed to offer less impedance than competing boards, lowering internal temperatures and increasing stability.

It’s impossible to realistically verify this, but we’ve been satisfied with the long-term reliability of Gigabyte products before.

All told, the EX58-UD5 is a top-quality board, but it carries a price tag to match. Core i7 is a premium platform, and if you’re buying in at this stage you don’t want a board that will hold you back.

There’s no such thing as a truly future-proof PC; but partner the EX58-UD5 with a fast Core i7 and you’ll be about as close as you can get.

7. Mini roundup: Four H55 motherboards using Intel's latest chipset

Intel’s H55 chipset supports integrated graphics on Core i3 and i5 CPUs.
We test four boards that take advantage

Price: $132

The Asus P7H55-M Pro is a typical offering. Its four DDR3 slots will take up to 16GB of RAM, and with six SATA connectors plus one PATA port it will accommodate plenty of drives - although there's no RAID support, and (this being 2010) no floppy controller either.

Expansion options comprise a single PCI Express x16 slot, one PCI Express x1 and two PCI slots, and on the backplate there are six USB sockets (with headers for six more), Gigabit Ethernet, a single PS/2 connector and 7.1 audio. Intel's on-chip GPU is served by VGA, DVI and HDMI ports.

The board has a few top-shelf features: DIMMs can be overclocked up to a crazy 2133MHz, and an eight-pin CPU power connector will reassure anyone looking to tax their processor. It supports Asus' fast-booting "ExpressGate" internet environment too, should that be of interest.

Power consumption in Windows is low, with our test system idling at 43W and hitting only 90W under peak load. In all the Asus is perfectly suitable for an everyday home or business PC, but it isn't the most generously-specified choice.

8. INTEL 865 / 865G

Intel's 865G chipset (codenamed Springdale), is almost identical to the 875 (Canterwood), and is designed to support the new Intel Pentium 4 processor with Hyper-Threading as well as the 800MHz frontside bus (FSB). It also includes 8x AGP, USB 2.0 and Serial ATA support.

Price:$83

Dual-channel DDR gives a performance improvement over single-channel, which is especially important for the Pentium 4, as it sports a faster system bus than the Athlon XP, and thus demands more memory bandwidth to get the most from the CPU. The memory performance is most noticeable in multimedia and 3D-intensive applications, which depend a great deal on the memory.The 865G platform has been specifically tailored for use as a stable platform for corporate and consumer users, while the 865P and PE boards are geared towards mainstream consumers and speed. The Intel 865G chipset also has optional Gigabit Ethernet, surround sound connectivity, Intel's Extreme Graphics 2 and SATA RAID with the ICH5R Southbridge. The cut-down 865P sports identical functions, although it operates at only 533MHz FSB and supports DDR333, not 800MHz and DDR400.

9. Gigabyte GA-MA78GM-S2H

A capable little package at an attractive price

Price: AUD $94

Gigabyte’s Intel-based motherboard is this month’s winner, but the GA-MA78GM-S2H gives you many of the same features in an AMD-compatible package.
It’s a cheaper and smaller board, using the microATX form factor, so not surprisingly it isn’t as versatile as its sibling. You get fewer expansion slots and, while the BIOS offers the same excellent support for overclocking the CPU, you can’t overclock memory in the same way. There’s no dual RAM support, either – you’re left with DDR2 only, although that’s hardly an imposition. And, surprisingly, you can fit up to 16GB of RAM.

The GA-MA78GM-S2H also has a particular strength of its own: an integrated Radeon HD 3200 GPU, complete with HDMI output, making it a splendid starting point for a budget desktop PC or entertainment system. The graphics are based on the same core as the old Radeon HD 2400 Pro, so it will decode HD video in hardware and can even run 3D games, but don’t expect high resolutions or awesome visual effects. The board supports Hybrid CrossFire, too, so you can pair the onboard graphics with a graphics card, squeezing a little extra out of a low-cost solution (see page 58).

10. MSI K9N2 SLI Platinum

A decent board, but the Hybrid SLI feature doesn’t justify the high asking price

Price: AUD $162

MSI’s latest AMD motherboard is the first we’ve seen with Nvidia’s nForce 750a chipset, the chief benefit of which is Hybrid SLI. This lets you combine the board’s integrated graphics with a discrete GeForce card to give better 3D performance.

It sounds exciting: in practice it’s anything but. The onboard GPU is a low-powered GeForce 8200 part, and it won’t partner with anything more powerful than an 8500 GT card. This doesn’t provide enough of a performance boost to make it a worthwhile addition to your PC – a $100 8600 GT running on its own will provide better performance.

Thankfully, the K9N2 SLI Platinum offers a decent range of benefits to make up for this uninspiring headline feature. Its backplane has a generous selection of ports, including DVI output, FireWire and two eSATA sockets. There are only four USB ports, but three internal headers allow for up to six more, two of which are on a supplied rear bracket.

It also has small onboard Power and Reset buttons – handy for tinkerers – and a button to clear the CMOS. There’s no internal POST readout, though, as found on some of MSI’s other high-end boards.

Expansion options are mostly typical: there are two pairs of dual-channel DDR2 DIMM slots, capable of running 8GB of RAM at up to 1066MHz with a Socket AM2+ processor. In addition to the two PCI Express 16x slots, there’s a single PCI Express 1x socket and two standard PCI slots.

And, on top of its six SATA ports (four of them side-mounted, so as not to interfere with graphics cards), the K9N2 Platinum offers two IDE connectors. Since most modern boards offer only one, this could make it a suitable board if you’re upgrading and bringing across multiple drives from an older system.

Cooling, meanwhile, is covered by MSI’s Circu-Pipe system – a good way to keep the chipset cool, but it involves two heatsinks that rise up from the board a mere 40mm away from the CPU socket on two sides. That could prove a problem if you want to use a wide CPU cooler.

The price, however, is this board’s main problem; there’s little here to justify paying $162 for. We’d advise buying a standard board and a decent graphics card instead.

In view of the above top 10 Motherboards of the New Technology is very imporant and useful, I have found that lot of the persons of the world has been purchased above mentioned Motherboards and not any complain has been received as yet.

By this article you will teach that how you wiring diagram of PCs power supply of DTK company. This power supply has ATX design and 200W performance. This power supply circuit uses chip TL494. Similar circuit is used in the most power supplies with output power about 200W.Device use push-pull transistor circuit with regulation of output voltage. I think line voltage goes through input filter circuit (C1, R1, T1, C4, T5) to the bridge rectifier. When voltage is switched from 230V to 115V, then rectifier works like a doubler. Varistors Z1 and Z2 have overvoltage protect function on the line input. Thermistor NTCR1 limits input current until capacitors C5 and C6 are charged. R2 and R3 are only for discharge capacitors after disconnecting power supply. When power supply is connected to the line voltage, then at first are charged capacitors C5 and C6 together for about 300V. Then take a run secondary power supply controlled by transistor Q12 and on his output will be voltage. Behind the voltage regulator IC3 will be voltage 5V, which goes in to the motherboard and it is necessary for turn-on logic and for "Wake on something" functions. Next unstabilized voltage goes through diode D30 to the main control chip IC1 and control transistors Q3 and Q4. When main power supply is running, then this voltage goes from +12V output through diode D. Now I describe following points step by step and look at the picture has given below:

1. Fuction of Mode Stand-By

In stand-by mode is main power supply blocked by positive voltage on the PS-ON pin through resistor R23 from secondary power supply. Because of this voltage is opened transistor Q10, which opens Q1, which applies reference voltage +5V from pin 14 IO1 to pin 4 IO1. Switched circuit is totally blocked. Tranzistors Q3 and Q4 are both opened and short-circuit winding of auxiliary transformer T2.Due to short-circuit is no voltage on the power circuit. By voltage on pin 4 we can drive maximum pulse-width on the IO1 output. Zero voltage means the highest pulse-width. +5V means that pulse disappear.

2. Function of running power supply.

Somebody pushes the power button on computer. Motheboard logic put to ground input pin PS-ON. Transistor Q10 closes and next Q1 closes. Capacitor C15 begins his charging through R15 and on the pin 4 IC1 begins decrease voltage to zero thanks to R17. Due to this voltage is maximum pulse-width continuosly increased and main power supply smoothly goes run.

In a normal operation is power supply controlled by IC1. When transistors Q1 and Q2 are closed, then Q3 and Q4 are opened. When we want to open one from power transistors (Q1, Q2), then we have to close his exciting transistor (Q3, Q4). Current goes via R46 and D14 and one winding T2. This current excite voltage on base of power transistor and due to positive feedback transistor goes quickly to saturation. When the impulse is finished, then both exciting transistors goes to open. Positive feedback dissapears and overshoot on the exciting winding quickly closes power transistor. After it is process repetead with second transistor. Transistors Q1 and Q2 alternately connects one end of primary winding to positive or negative voltage. Power branch goes from emitor of Q1 (collector Q2) through the third winding of exciting transformer T2. Next throug primary winding of main transformer T3 and capacitor C7 to the virtual center of supply voltage.

3. Function of Output voltage stabilization

Output voltages +5V and +12V are measured by R25 and R26 and their output goes to the IC1. Other voltages are not stabilised and they are justified by winding number and diode polarity. On the output is necessary reactance coil due to high frequency interference.

This voltage is rated from voltage before coil, pulse-width and duration cycle. On the output behind the rectifier diodes is a common coil for all voltages. When we keep direction of windings and winding number corresponding to output voltages, then coil works like a transformer and we have compensation for irregular load of individual voltages.

In a common practise are voltage deviations to 10% from rated value. From the internal 5-V reference regulator (pin 14 IC1) goes reference voltage through the voltage divider R24/R19 to inverting input(pin 2) of error amplifier. From the output of power supply comes voltage through divider R25,R26/R20,R21 to the non inverting input (pin 1). Feedback C1, R18 provides stability of regulator. Voltage from error amplifier is compared to the ramp voltage across capacitor C11. When the output voltage is decreased, then voltage on the error amplifier is toodecreased. Exciting pulse is longer, power transistors Q1 and Q2 are longer opened, width of pulse before output coil is grater and output power is increased. The second error amplifier is blocked by voltage on the pin 15 IC1.

4. Functions of PowerGood Signal

Mainboard needs "PowerGood" signal. When all output voltages goes to stable, then PowerGood signal goes to +5V (logical one). PowerGood signal is usually connected to the RESET signal.

5. Functions of Voltage +3.3V stabilization

Look at circuit connected to output voltage +3.3V. This circuit makes additional voltage stabilisation due to loss of voltage on cables. There are one auxiliary wire from connector for measure 3.3V voltage on motherboard.

6. Functions of Overvoltage circuits

This circuit is composed from Q5, Q6 and many discrete components. Circuit guards all of output voltages and when the some limit is exceeded, power supply is stopped.

For example when I by mistake short-circuit -5V with +5V, then positive voltage goes across D10, R28, D9 to the base Q6. This transistor is now opened and opens Q5. +5V from pin 14 IC1 comes across diode D11 to the pin 4 IC1 and power supply is blocked. Beyond that goes voltage again to base Q6. Power supply is still blocked, until he is disconnected from power line input.

How to use types of Motherboard

noreply@blogger.com (GM Qazi) — Wed, 06 Apr 2011 07:15:00 +0000

By this article you learn that how you purchase what types of Motherboard , I have given list of following useful and very good technology Motherboards as per your requirement please follow the following instructions.

Types of Computer Motherboards

Well, of course, after the discussion that we had above, you must be wondering how to determine a motherboard type. But before starting off with this process of describing the computer motherboard type, we need to understand, what are the different ways of classifying or rather differentiating computer motherboards.

1. Classification on the Basis of Type of Processor

This way of differentiating computer motherboards is based on motherboard socket types. In short, the CPUs that are available in the current market are compatible to specific motherboards. Let us try to understand the different CPU specific computer motherboards in a little more detail.

2. Socket A Motherboards

These motherboards are meant for the AMD and Durons processors. The Socket A motherboard is also known as Socket 464 motherboard. The CPU socket in the motherboard has 462 pins and it comes in a PGA (Pin Grid Array) packaging. The bus speed of this type of motherboard is 100 to 200 MHz.

3. Socket 370 Motherboards

Meant for Intel Pentium III and Celeron processor, this motherboard comes for CPUs with 370 pins. It can also support VIA Cyrix III and VIA C3 processors. The bus speed for this type of motherboard is 66 to 133 MHz and it also comes in a PGA package.

4. Socket 378 Motherboards

This type of motherboard is meant for the Pentium 4 processors. It also comes in a PGA package and has 478 pins. The bus speed is 100 to 200 MHz. This motherboard can also support Intel Pentium 4EE and Intel Pentium M processor. This type of motherboard is also known as Socket N motherboard.

5. Socket T Motherboards

Also known as LGA 775, this type of motherboard is meant for Intel Core 2 Duo, Intel Core 2 Quad and Inel Xeon processor. Of course, this motherboard can also support other Intel processors such as the Celeron, Pentium 4, Pentium D, Celeron D and Pentium XE processor. Its specifications include 775 pins and a very high bus speed of 1600 MHz. It also comes in a PGA package.

6. Socket 939 Motherboards

The Socket 939 is meant mainly for the AMD family. It can support AMD processors like the Athlon 64, Athlon 64 FX, Athlon 64 X2 and Opetron. It has 939 pins and can have a bus speed from 200 to 1000 MHz. Just like the other computer motherboard types described above, it also comes in a PGA package.

7. Socket AM3 Motherboards

Socket AM3 is among the most recently developed motherboards. Introduced in 2009, this motherboard is meant for the AMD Phenom II and AMD Athlon II processors. It has 941 pins and a bus speed range of 200 to 3200 MHz. The packaging for Socket AM3 motherboard is PGA.

8. Socket H Motherboards

The Socket H or LGA 1156 is another recent motherboard that has been introduced in the year 2009 and is meant for the Intel Core i3, Intel Core i5 and Intel Core i7processors. It has 1156 pins and comes in LGA (Large Grid Array) packaging.

9. ATX Motherboards

The ATX (Advanced Technology Extended) motherboard has a length of 12 inches and a width of 7.5 inches. The I/O ports and USB ports meant for the motherboard are integrated directly into it. The bus speed in ATX motherboard is 100 MHz. This board is mainly meant for the Intel processors.

10. Full AT Motherboards

This was the first type of motherboard, which was 12 inches wide and 11 inches long. This motherboard suffered from a lot of problems like access to components was cumbersome and most importantly, the heating problem.

11. Baby AT Motherboards

With a dimension of 10 by 8.5 inches, this motherboard is meant for the classic Pentium processors. The DIN keyboard connector at the top right corner of this motherboard makes recognizing this motherboard a relatively simple task.

I hope you have seen and study about above motherboards are very useful, these types of Motherboard are very useful and consisting of great technology if you want to purchase any types of Motherboard please read this article with carefully.

How to repair Power Supply for Computer

noreply@blogger.com (GM Qazi) — Wed, 06 Apr 2011 06:33:00 +0000

By this article you teach that how you repair and replace Power Supply and how you fix and solve the problems on urgent basis. If you want to replace your desktop PC Computers power supply unit. In this step by step guide we show you what is involved. Not so long ago, when a PC failed, most people just went out and bought a new one. But in these austere times, people are thinking twice before throwing out an older computer that might be easy to fix. Replacing your Computer Power Supply unit is one of the easiest and cheapest repairs that you can do. As long as you are handy with a screw driver and you do not mind opening your computer, you should be able to carry out this repair. Now follow the following instructions with carefully.

Safety warning and precautions

As with any electrical device, you need be very careful when opening up your PC. You are dealing with electricity which kills. The number of people who get a nasty shock because the Computer is still plugged in is legion. Make sure you disconnect your PC from the mains electricity supply before you start, and as an added precaution, stop and check that the electrical socket where the computer had been plugged in is empty. Please make absolutely sure that your computer is not plugged into the mains electricity.

Use Plastic handled screw driver

As an added precaution, you might also consider using a grounding strap, also sometimes called an anti static wrist strap. A grounding strap can help to prevent damage to your Computer due to electrostatic discharge (ESD) by safely grounding you while you work on your computer.

How do you know about replacement of Power Supply

I am assuming that your knowledge of electronics is fairly basic, so that the diagnostic options available to you are fairly limited. Here are some indications that your Power Supply has failed, or may be on its way to failing.

• There is no power going to your computer or to any of its internal peripherals

• There is a burning smell coming from the power supply

• It’s difficult to switch on your computer, by which I mean it takes several pushes of the on/off
button for the computer to boot.

Of course, if you are more electronically minded, you could use a multimeter to test the current coming from the power supply unit (but please do not try to do this unless you know what you are doing, and can do so safely. Before you go down the path of replacing your Computers Power Supply, it is also worth making sure that the wall socket is working by plugging something into it and turning that something on. You should make sure the power strip (power board) is working the same way (if one is in use). You should also try using a different power cord. These are pretty common. If you do not have a spare power cord to hand, try the one for the monitor, which is probably the same. If you do not know for make sure that your Power Supply has failed, you may find that you replace your Power Supply, and your PC still does not work. In this case, you need to consider whether it is worth the risk of spending more money so it will cost to buy a new Power Supply and possibly find that there is another problem with your computer.

Check result before you start

Make sure you have got the right replacement Power Supply. These can be readily purchased from Computer parts shops.To check what kind of Power Supply you need to get, look at the sticker on the existing Power Supply you will need to open your Computer to do this. In case it read “A350w ATX P4 power supply” this meant I needed an ATX power supply unit. There are three types of power supply in common use:

• AT – used in older PCs
• ATX – used in more recent PCs
• ATX V2 (also known as ATX12V

A newer type of power supply designed for the power requirements of modern PCs. Generally speaking, you should be able use an ATX V2 PSU with an older computer that had an ATX PSU. ATX V2 has a 24 pin connector going to the motherboard, while ATX has a 20 pin connector, but as discussed below, you should be able to work around this.

You will find a very useful article about ATX and ATX V2 Power Supplies here.If there is no sticker visible on the Power Supply, find out what kind of motherboard you have got, and use Google to find out what kind of Power Supply it works with. Alternatively, remove the Power Supply from the machine following the instructions below and take it with you when you go to buy a replacement Power Supply and make sure that the new Power Supply has at least the same number of watts as the old power supply.

How to replace a PC power supply on urgent basis

1. Turn off your computer if the PSU has not failed completely, and it happens to be powered up and unplug the power lead from the mains.

2. Remove the cover or access panel, this will depend on your Computer case. With my PC, I was able to remove a side access panel, but you may need to remove screws and take off the whole cover. You might find it easier to work on your computer if its is laying on its side. Follow the picture given below for more guidance.

3. The power supply is usually located at the top, back of the case. It will usually be secured by four or so screws. The mains power lead plugs into back of the Power Supply the side that backs onto the rear of the Computer case. On the front of the Power Supply the side that faces the inside of the computer you will see a number of cables leading to the motherboard and DVD drives, hard disks etc. For more information follow the picture has given below:

Gently pull out these leads from their sockets. You might need to use your thumb to release the catch that secures the connectors to the motherboard. Take note of which lead goes where. While it’s hard to plug connections into the wrong sockets, you will find it easier to put your Computer back together if you note what goes where. One colleague suggested taking a digital photo of where the cables go while everything is still in place, while another uses sticky labels on both the sockets and cables to help him remember what went where. He puts one label on the socket from which he is removing a cable and marks it ‘A’, and then wraps a label around the cable he is removing and marks that ‘A’ as well. And another colleague suggested drawing a diagram of which lead goes where. Obvious, use whatever system will work best for you. For more guidance follow the picture has given below:

4. Now we need to remove the power supply. In my case this was down by removing the four screws that secured the power supply to the chassis of the computer, and then sliding it out of its position. For more guideline show the picture below:

5. Take the new power supply, put it in place, and tighten the screws that keep it in place. I have read it well for more information see the picture below with carefully.

6. Attach the two motherboard cables to the motherboard. If you have an older computer, and you’ve bought an ATX 2 power supply, you may find that the main motherboard connector has four extra pins (see picture, above). You should be able to detach these extra pins so that the plug fits, or if this is not the case, hope that there is enough clearance to right of the socket on the motherboard to accommodate the extra pins.

7. Reattach the power leads for the hard disks and optical drives, and any other component that draws power.

8. Replace the cover.

9. Plug in the power lead to the back of the machine, and switch on your computer.

All going well, your PC should come to life. if it does not disconnect the power lead from the mains, and open up your computer. Check all the connections, especially the leads running to the motherboard, and try again. If you are confident that all the connections are correct, it may be that there is another fault that is stopping your PC from working.

Clean Bad Sectors from Hard Disk

noreply@blogger.com (GM Qazi) — Wed, 15 Dec 2010 06:55:00 +0000

This is very informative and good software it is very small and easy software called (SEAMAP) to clean Bad Sectors from the Hard Disk. According my experience in the field of Computer, I have cleaned and made of Hard Disks and removed bad sectors with successfully. I want to discuss that there are two kinds of Bad Sectors called Logical Bad Sectors and Physical Bad Sectors. To clean the Bad Sectors we use different ways for both. Logical Bad Sectors affects due to Virus attack and other problem is to restart system time to time and engage the Hard Disk long time and also cause of big software which installed on the system or failure of Power Supply and lot of reasons of Bad Sectors. Now I am giving the best way to clean the bad Sectors. I strongly say that when using of the Sea Map Software all partitions of the Hard Disk has been moved automatically, you should be made partitions again. I am showing following pictures to easy and best way to clean the Bad Sectors. When you start Sea Map you will look at the following picture:

Now you will set options press "SD" and you will look set Drive options Press "0". Here is important is that before to do this you will set Hard Disk Write protect option, Yes/No, then you will set "N" for write protect of Hard Disk than press "Esc" button and goes to Command line. Look at the following pictures with carefully:

After that you will start the work and press Command "FD" for format of Drive for low level format press "Y" now sea Map has started work have patience one to two hours, when format over message appeared, than you should make partitions with the support of "FDISK" and start normal format look at the following pictures for guidelines:

Use of DVD Disk and Bluray

noreply@blogger.com (GM Qazi) — Wed, 15 Dec 2010 06:12:00 +0000

DVD DISK

DVD means Digital Versatile Disk,it was made first time in 1996, it is like common CD but its capacity is very large than the CD, when it was made every one called Digital Video Disk but we can not change its original name Digital Versatile Disk. There are two kinds of DVD

1. Single Sided DVD

it is store 4.7 GB Data on Single layer and 8.5 GB Data on Daul layer

2. Double Sided DVD

it is store 9.4 GB Data on Single layer and 17 GB Data on Daul layer

It is very important and good result of DVD to see the movie with high quality resolution. The reason is that when we compress the video file its result is not looking better than we uncompressed it. The width and capacity of the DVD is very large we can copy any movie with high resolution and with good quality and pixels not looking on it and sound is very clear.

How Clean DVD Disk

This is very simple how clean of DVD Disk, I will tell you that your precious movies and other data are saved in the DVD you can not kept it another place to use DVD Disk it has been scratched and not giving best result.Take some tooth paste and rub on DVD Disk and leave him for dry after half an hour clean your DVD Disk with Thinner and soft cloth, the result is that your DVD changed in new condition.

BLURAY DISK

This is new Technology was made by Blu-Ray Disc Association with Associate by the Sony, Dell, Hitachi, LG, Panasonic,Sam Sang and other companies. Blu-Ray save and Read the Data through Blue-Violet radiation and we use normal DVD and CD it read and save the data through Red Radiations.

1. Single layer Blu-Ray Disk = 25 GB

2. Double layer Blu-Ray Disk = 50 GB

Blu-Ray Disk was made specially to save high definition HD Videos. Blu-Ray can read the format of DVD and CD with easily. Blu-Ray transfer his data by 36 mbps it is also recording the paly back of HDTV. In the coming days Blu-Ray will be very useful technology.
