Error starting program. There is not enough memory. Quit some programs and try again.

2011-06-22T21:50:00.000+08:00

Your computer may need more memory (RAM).

You may have too many programs running at one
time and resources have been depleted. This includes TSRs that may be running in the background.

Do you have a large array of icons in your system tray on the taskbar? Press CTRL-ALT-DEL and see how many programs are running. You may have to close some down to regain resources.

Remember also,that some programs not currently running may not have released memory and other resources properly at shut-down. In this case you may need to turn off your computer, wait 30 seconds or so, and restart it.

Also, check to see if your hard drive is getting full. Windows requires free space on your hard drive to use as a swap file, or virtual memory. I suggest leaving about 25% of your hard drive free (at least the drive that contains your operating system files). Some people consider this a little extravagant, but if you want to push the edge, then be prepared to deal with the consequences.

Delete unnecessary files from your hard drive. Empty your Recycle Bin and your Internet Browser's cache. Do a ScanDisk and defragment your hard drive.

Keyboard Error

2011-06-22T21:46:00.000+08:00

If your keyboard isn't plugged in, you'll get a keyboard error at startup.
You might also have touched a key during startup, or perhaps there's a book or something pressing on the keyboard.
However, if its recurring, you may want to check for sticking or broken keys, or get a new keyboard.

Invalid System Disk. Replace the disk and then press any key

2011-06-22T21:43:00.000+08:00

You have tried to start your computer with a disk in the floppy drive that doesn't contain any operating system files.

Solution: all you have to do is remove the disk and press the spacebar. Or go to BIOS and choose the appropriate System Disk.

Confirm that your hard disk or file system is not damaged

2011-06-19T20:19:00.001+08:00

Confirm that your hard disk or file system is not damaged. Start your computer from the Windows XP CD-ROM, load Microsoft Recovery Console, and then use the Chkdsk command-line utility. This may solve your problem.

Important We recommend that advanced users or administrators use the Recovery Console. You have to know the Administrator's password to use the Recovery Console.

For additional information about how to check and repair a damaged hard disk by using Chkdsk, see the "Using the Recovery Console" and "Using the Recovery Console command prompt"

How to install and use the Recovery Console in Windows XP

Note If the Chkdsk command reports that it cannot gain access to your hard disk, you may have a hardware failure. Examine all cable connections and any jumper settings on your drive. For more assistance, contact a computer repair professional or the manufacturer of your computer.

If the Chkdsk command reports that it cannot fix all hard disk problems, your file system or Master Boot Record (MBR) may be damaged or no longer accessible. Try appropriate Recovery Console commands such as Fixmbr and Fixboot, contact a data recovery service, or repartition and reformat your hard disk.

Important For more help, contact your computer manufacturer or a Microsoft Product Support Services professional.

Allow only qualified personnel to repair your computer. Computer repair that is performed by non-qualified personnel may nullify your computer's warranty.

If you repartition and reformat your hard disk, you lose all the information on the disk.

Determine if a new program was recently installed on your computer

2011-06-18T17:44:00.001+08:00

If you recently removed a program or a Windows component from your computer by deleting it manually, related information that is still on your computer may be causing the problem. To remove the program or component, first reinstall it, and then use the Add or Remove Programs tool, or follow the manufacturer's instructions.

To remove a program from your computer, follow these steps:

1. Click Start, click Control Panel, and then click Add or Remove Programs.
2. In the list of programs, click the one that you want to remove, and then click Change/Remove.
3. Click Yes when you are prompted with the question "Do you want to remove the program?"

If the program is not listed in the Add or Remove Programs tool, contact the manufacturer to obtain instructions for removing it.

Proccessor packages

2011-03-15T12:47:00.000+08:00

DIP - Dual Inline Package

- The old standard for chip design.
- Will always have an even numbers of pins.
- Pin count can be as low as 4 and as high as 68
- In μps, this is used in older 8086, 8088 and 8026 models.

PIN GRID ARRAY

- The rows are changed to an array of pins.
- A square chip with several rows of pins evenly spaced around the perimeter of the chip to form the array.

- Two PGA sockets

a) regular - Chip is inserted the same way as DIP
b) ZIF - Zero Insertion Force, has a lever machanism that will open the socket and allow the chip to be inserted w/ no force.

- In μps, this is used in 80286, 80386, 80486, Pentium, Celeron and most non-Intel processors.

- Different modifications of PGA

º Stagered Pin-Grid Array (SPGA) - Used in Pentium processors, which staggers the arrangement of the pins to allow them to fit closer together.

º The Pentium Pro, because it has seperate chips for theCPU and the Level 2cache, uses a design called the multichip module (MCM). An MCM is a package that contains more than one chip.

º Tape-Carrier Package (TCP) - Which is as thin as phographic film and is soldered to the motherboard.

º Single-Edge Contact (sec) cartridge, used for the Pentium ll. This is actually a PGA package mounted on a small daughtercard tat attaches to the motherboard through a single-edge connector The SEC is a highly appealing in design, because it takes up less space on the motherboard and has better electrical characteristics.

Organic land Grid Array (ool or OLGA).

- The OLGA chips uses a flip chip design, where the processor is attached to the substrate facedown for better signal integrity, more efficient heat removal and lower inductance Used by the Pentium 4 processor, which has 423 pins.

Types of Ports

2011-02-16T21:29:00.000+08:00

In computer hardware, a port serves as an interface between the computer and other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects. Electronically, the several conductors making up the outlet provide a signal transfer between devices.

Serial Port

send and receive one bit at a time via a single wire pair (Ground and +/-).

Parallel port

send multiple bits at the same time over several sets of wires.

USB Port

Can connect up to 127 different peripherals

FireWire Port

Previously known as IEEE 1394 port. Can connect up to 63 devices.

Peripheral

2011-02-16T21:25:00.000+08:00

is a device attached to a host computer, but not part of it, and is more or less dependent on the host. It expands the host's capabilities, but does not form part of the core computer architecture.

Examples are Digital Cameras, Image Scanners, Webcams, Microphones, Loudspeakers, Tape drives, and Computer Printers.

Speed Up Your Computer

2011-02-12T00:41:00.000+08:00

If you want to improve the speed of your computer, that’s great. However, above all, do no harm and beyond the scope of this Windows forum, ask for help from those you know if you get in over your head. Remember: you have time. You can stop most processes I discuss without causing harm. Caution and common sense go a long way when working with computers; problems are often much easier to fix than they appear.

1. Make Sure Your Hardware is Sufficient

Above and beyond everything you can do with software to optimize the function of your computer, making sure you have the proper hardware to support Windows is critical.

2. Clean Your Desktop

Is your Windows Desktop dotted with files? Have you noticed that your computer has been running slower and slower? Do you see the hard drive light often flashing while you wait for the computer to respond to an action? There are steps you can take to fix it. Read this article.

3. Scan Your Windows System for Errors

An operating system is a collection of files that perform different functions. It is possible, over time, that one or more of these system files has changed or become corrupted. If this happens, the speed of your system may decrease. By using a utility called “System File Checking”, it will inspect these files and correct any problem it finds.

4. Scan for Viruses, Spyware and Adware

Every Windows computer is vulnerable to viruses. Viruses are nasty little programs that cause both major and minor problems for users.

Spyware and Adware are programs created by companies to find out more information about customers, so they can better market products to them. Usually these programs are not created for malicious purposes. Spyware and Adware can load into computer memory and slow it down.

Periodically scanning and removal of Viruses, Spyware and Adware is a great way to improve computer performance.

5. Uninstall Unused Programs

Over time, you may have accumulated programs on your computer that you do not use. When a program is installed, it creates connections between the program and the operating system. Even if you don’t use these programs, they can slow down your system. If you have the original program’s installation disk or file, removing programs will free up space on your computer and may speed up your system's performance.

6. Adjust Visual Effects for Better Performance

Windows provides a number of interesting visual effects including animated windows and fading menus. If you do not have enough operating memory (see above number 1), these effects can slow down your computer. Adjusting or reducing visual effects can make a difference.

To speed up Vista computers in particular you can disable features and function that are not used. For more information, read "How to Speed Up Windows Vista."

7. Don’t Automatically Start Programs

Programs use operating memory (RAM, also called system resources). Unless you always use these programs, you can keep them from loading at Windows startup and speed both the booting of your computer and its performance.

8. Defragment Your Hard Drive (After you have tried everything else)

The more information and programs you have on your computer, the more it is likely that Windows has placed parts of the same file in different locations on your hard drive. It may do this for hundreds of files and programs, depending on how much space is available. Defragmenting the hard drive places all information for each file in one place. The result can be a faster computer experience.

Important Note: Before you even try this, backup all your work onto a different computer, hard drive, CD or disk. Also, you should only do this if you have a reliable source of power for your computer. Doing this when there is a brown out or power problem in the neighborhood, is not a good idea. If a computer turns off while it is defragmenting a drive, it will create more problems than not defragmenting it in the first place.

9. Reinstall the Operating System and Programs

If you have done all the above steps and your computer does not become more responsive, you might consider reinstalling the operating system and programs. This is a scorched earth option - basically you backup all your data and user settings, wipe your hard drive clean and re-install the operating system with your original disks. Next, install all your favorite programs and restore all your data and user settings.

The nice thing about doing this is that you essentially have a new computer, free of years worth of software and registry changes, additions and errors that can turn a fast rabbit of a Windows computer into a slow turtle. The bad thing about this choice is that it takes time and planning to do it correctly. If your PC is 3 to 4 years old and continues to run slower than it did when you purchased it, this might be the only action that will make a significant difference.

Error Messages on Start Up

2011-02-08T21:40:00.000+08:00

Error messages like nwlink.vxd missing or damaged - press any key to continue may lead you through several messages before starting Windows. It is certainly an inconvenience to keep pressing 8 to 10 keys each time you want to start Windows.

This is caused by the incorrect deletion of programs. When removing a program from a computer you need to use the Add/Remove Software in the Control Panel to actually un-install it rather than delete it.
Just deleting a program is likely to give you these error messages.

Solution: Just don't do it again. (The problem can be solved by editing the ini files and the registry but that as that is a risky proposition you may just want to put up with the inconvenience till you next format your hard disk and re-install Windows).

Modem cuts off frequently

2011-02-08T21:39:00.000+08:00

Modems cannot handle the beep on BT's call waiting facility. If you have call waiting on your line you will need to disable it before using the modem.

Fuzzy image on monitor

2011-02-08T21:34:00.000+08:00

Ensure that your speakers are not too close to the monitor and that there is no other source of interference, especially from TVs, radios, microwaves, dishwashers and washing machines.

-Monitors are sensitive to electro magnetic interference.

-Mobile phones are frequently the cause of this problem.

Computer seems to start up as normal but nothing appears on screen

2011-02-08T21:32:00.000+08:00

As obvious as this may sound it is probably a cable not attached correctly, or the monitor power button being turned off. Please unplug all the cables and replace them carefully.

Or!!!

The possible reason is that your graphics card is defective and have it replaced.

No sound from speakers

2011-02-08T21:31:00.000+08:00

Please check at the back of the computer. Some computers may have speaker connections on both the soundcard and modem. You will need to plug the single stereo speaker plug into the socket on the soundcard usually marked Audio Out (or in some cases Speaker)

Or!!!!!

You probably did not install the audio driver.
Please install your audio driver and after installing it restart the system.

"Original Microsoft installer is Recomended"

"There's a new Windows 7 installer from Microsoft. Most of the virus in Windows XP will not work in Windows 7".

Windows restarts without warning.

2011-01-26T20:20:00.000+08:00

Cause:

This issue could be caused by any of the below possibilities.

1.Software issue or error.
2.Hardware issue or error.
3.Heat related issue.
4.Computer virus.
5.Issue with operating system.

Software issue or error

Errors generated by software programs can cause a computer to reboot unexpectedly or without warning. If you are running Windows XP see the below section "For Windows XP users" before continuing.

If you are not running Windows XP or following the below steps still cause your computer to reboot without warning. Boot your computer into Safe Mode, and let the computer run in Safe Mode.

If the computer is still rebooting in Safe Mode the issue is likely not software related but something else, skip to the next section. If the computer is not rebooting in Safe Mode it is likely you have software related issue. We would recommend you run through the basic troubleshooting section for your operating system.

For Windows XP users

Windows XP is designed to automatically reboot each time an error occurs such as a BSoD. Although this may be nice for errors that do not occur often, users who have a re-occurring error may wish to identify the error to troubleshoot it. Below are the steps on how this feature can be disabled and enabled in Windows XP.

1.From the desktop right-click on My Computer.
2.Click the Properties option.
3.In the System Properties window click the Advanced tab.
4.In Advanced click the Settings button under Startup and Recovery.
5.In the Startup and Recovery window uncheck the Automatically restart check box.
6.Click Ok.

Now if the computer generates and error it should not automatically restart and enable you to display any errors your computer may be experiencing.

Hardware issue or error

Some of the below steps require you open your computer. While in the computer, be cautious of ESD.

Any failing hardware component in your computer could cause your computer to unexpectedly generate an error or reboot without warning. If you have recently attempted to add a new hardware device, remove that device to make sure it is not causing your issues.

Make sure you are not encountering any hardware conflicts by viewing Device Manager for errors.

New drivers can also cause this issue, if you have recently performed any hardware driver updates you may wish to try an earlier version of the drivers. Additional information and help with computer drivers can be found on our drivers page.

If you have updated drivers and removed any hardware that could be causing this issue and continue to experience random reboots, it's possible that the memory is bad in the computer.

How can I test my memory to determine if it is bad?
Finally, hardware devices that are not installed properly in the computer can also cause random reboots. Make sure all the cables and expansion cards are connected properly to the computer. The best way to determine this is to disconnect and reconnect all cables and expansion cards.

Computer virus

Computer viruses such as the blaster virus are written to reboot your computer without warning. Usually these viruses will make the computer reboot ever 5, 10, 15 or 30 minutes after the computer has booted.

If you believe your computer may be infected with a virus or are uncertain if your computer is infected with a virus make sure your virus scanner definitions are up to date.

How do I update my antivirus program?
Heat related issue

Many computer today are designed to turn off or automatically reboot if the computer, processor, or other device in your computer gets to hot. If you have heard any abnormal noises coming from your computer recently such as a high squealing this could indicate a fan may be failing in your computer.

First, verify the fan on the power supply is working by examining the back of the computer and seeing if the fan is moving and moving smoothly. For all other fans in the computer you will need to either open the computer and verify all fans are working, e.g. processor fan and case fan.

If your BIOS monitors the RPM of the fans enter CMOS Setup and verify it does not report any errors.

What temperature should my processor be running at?
Issue with operating system

If after following each of the above recommendations your computer still continues to reboot it is likely that you are experiencing a Microsoft Windows operating system related issue that cannot be explained. To help make sure this is the case try the below steps.

1.Reboot the computer and enter CMOS setup as the computer is booting.
2.After you have loaded the computer in CMOS setup let the computer sit.
If the computer does not reboot while letting the computer sit in CMOS it is likely that you are in fact experiencing an issue with Microsoft Windows and it is recommend that if you have followed all of the above recommendations that you reinstall Microsoft Windows.
