Fix blue screen errors

noreply@blogger.com (Austin) — Sun, 25 Oct 2009 07:20:14 PDT

Blue screen errors vary based on the type of error codes. they are usually associated with hardware problems. when a blue screen error comes up, it results from some sort of hardware incompatibility. you would notice a memory code next to them like the following 0x000000@# where @# can be any hexadecimal code. based on the error code, we troubleshoot. when you get a blue screen code, just note down the error code and do a google search on it and then you should find the cause and the right troubleshooting steps.

There are several ways in which you can try to correct this problem which is mostly caused by Wrong Drivers on An update of a Driver that isn't compatible with your hadware. Try to search the web with the Error code generated by your system i.e type the error code and click search. once you know which device is causing the error,check to see if it had any Driver updates and try to Roll back the Driver installation. You can also try to do a system restore and choose a time earlier that the the day of System update dates.

Restart your computer in safe mode then Click Start,-All Programs,- Accessories,- System Tools,- system Restore. choose a restore point earlier that than your last two or three updates and start restore.

Microsoft Knowledge Base

noreply@blogger.com (Austin) — Sun, 25 Oct 2009 07:15:49 PDT

The Microsoft Knowledge Base contains many articles that explain specific STOP error messages, and resolutions or ways to work around problems. Search the Microsoft Knowledge Base for at least the first hexadecimal number contained in the error message. Using the example above, search for 0x0000001e. It also may be helpful to search for the identified file name and other hexadecimal numbers.

Preparation to Create a Memory.dmp File

1. Verify that your computer is set to write a Memory.dmp file (in Control Panel, double-click System, and then click the Startup/Shutdown tab).
2. Click to select the Write an event to the system log and Write Debugging information to check boxes.

Speeds Windows Vista performance

noreply@blogger.com (Austin) — Sun, 30 Aug 2009 00:59:35 PDT

Windows Vista's ReadyBoost feature allows Windows to treat a USB flash drive as a disk cache. What does that mean?
Disk caches are one way of coping with the inefficiencies of hard disk drives, which are the slowest component in most computers. Any time the computer reads data from or writes data to the hard disk, it must stop and wait for the operation to complete.
In disk caching, an area of memory is reserved for storing copies of recently used or commonly used files. When these files are requested again, Windows can read the files from the cache, which is much faster than the hard disk.
The problem with disk caches implemented by the operating system is that they consume system RAM, leaving less RAM available for other tasks. This is why the size of the disk cache is limited. This is paradoxical. Larger caches mean better performance, but larger caches consume more memory, which has the effect of diminishing performance. But what if you could increase cache size without consuming additional system RAM?
This is exactly what Windows Vista's ReadyBoost feature does. ReadyBoost allows Windows to treat a USB flash drive as a disk cache.

speed up Windows Vista Performance

noreply@blogger.com (Austin) — Sun, 30 Aug 2009 00:15:25 PDT

Disable File Search Indexing (which includes processes – SearchProtocolHost, SearchFilterHost and SearchIndexer) in Windows Vista to substantially boost performance. This is a windows service which runs in background always accessing harddisk and network resources. If you disable this, windows search may not be accurate, but that is something I don’t care.

Disbling Windows Search Service is simple. Open up Control Panel -> Administrative Tools -> Service. Find a service named Windows Search. Stop this service and change its startup type to manual. If you want, you can manually run the service when you are not using your system.

Once I disabled this, I found that harddisk access reduced substantially and also my internet connection was running in top speed.

Is Your PC Performing Badly? Scan for Windows Registry Errors with RegCure

PC performance inevitably becomes jaded over time for various reasons. Possibly the most common problem with any computer that many people try to ignore is that it becomes sluggish at best. Many computer users suffer the problem but simply believe it to be a symptom of use or age. This is unlikely to be the case and there is usually a much more specific and, more importantly, curable reason.

Fatal Errors And Exceptions

Fatal errors are not only annoying but can also cause the loss of work and serious frustration and anger. When the blue screen starts to appear it is sometimes considered the beginning of the end of a computer’s life. Some users may consider trying a system restore to a time when there computer worked well enough but may purchase a new computer in preference to hunting down the real cause of the problem.

Detect and repair disk errors computer

5 ways to speed up your PC

By following a few simple guidelines, you can maintain your computer and keep it running smoothly. This article discusses how to use the tools available in Windows XP Service Pack 3 (SP3) and Windows Vista to more efficiently maintain your computer and safeguard your privacy when you're online.
1. Free up disk space

By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:

*

Remove temporary Internet files.
*

Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
*

Empty the Recycle Bin.
*

Remove Windows temporary files.
*

Remove optional Windows components that you don't use.
*

Remove installed programs that you no longer use.

Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.

To use Disk Cleanup

1.

Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.

Image of Disk Cleanup dialog box
2.

In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.
Image of Disk Cleanup for dialog box

Choose the files that you want to delete.

3.

Clear the check boxes for files that you don't want to delete, and then click OK.
4.

When prompted to confirm that you want to delete the specified files, click Yes.

After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.
2. Speed up access to data

Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.

Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.

When to run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals—monthly is optimal—there are other times you should run it too, such as when:

*

You add a large number of files.
*

Your free disk space totals 15 percent or less.
*

You install new programs or a new version of Windows.

To use Disk Defragmenter:

1.

Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.
Image of the Disk Defragmenter dialog box

Click Analyze to start the Disk Defragmenter.

2.

In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.

Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
3.

To defragment the selected drive or drives, click the Defragment button. Note: In Windows Vista, there is no graphical user interface to demonstrate the progress—but your hard drive is still being defragmented.

After the defragmentation is complete, Disk Defragmenter displays the results.
4.

To display detailed information about the defragmented disk or partition, click View Report.
5.

To close the View Report dialog box, click Close.
6.

To close the Disk Defragmenter utility, click the Close button on the title bar of the window.

3. Detect and repair disk errors

In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.

If you use your computer daily, you should run this utility once a week to help prevent data loss.

To run the Error Checking utility:

1.Close all open files.
2.Click Start, and then click My Computer.

#In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
#In the Properties dialog box, click the Tools tab.
#Click the Check Now button.
In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
7.If bad sectors are found, choose to fix them.

Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.

Internet Connection Troubleshooting

noreply@blogger.com (Austin) — Sun, 26 Apr 2009 21:23:35 PDT

Step1
Power cycle the arrangement by shutting it down and switch it on after at least 30 seconds.
Step2
Call your ISP to determine if there is trouble at their end. Quite often service is temporarily impaired at the ISP site due to maintenance purposes, construction in the vicinity or after a spell of rough weather. Ask them if your payment is overdue. Subscribers opting for automatic payments may forget to pay the bill if their credit card expires. The ISPs in such a situation may cancel the subscription without notifying the consumer.
Step3
Use ping at the command prompt to see if your computer can establish a connection. Your computer failing to connect to the remote host indicates a trouble on your Internet connection. You can ping any Web site. For instance, click on Start and then Run in Windows; type "cmd" to open the command prompt, and type "ping www.yahoo.com". Not getting a response would usually indicate a trouble from the ISP’s end.
Step4
Use the Tracert mastery to look at the complete route your request takes before displaying the desired Web page. The first few routers listed in the command results indicate ISP router activity. Regular use of Tracert therefore gives an idea if the ISP's routers have slowed down. If this is the case, you can call your ISP and bring the slow functioning router to their notice. Tracert results also show if any other router in the network is slow. In this situation, you cannot do much aside from waiting for the trouble to get fixed and visiting another Web page.
Step5

Check the cabling. All wires should be connected properly. Fix loose connection(s), if any. A cable not connected to a power supply or switches not turned on are most common oversights. Hear the click sound when inserting cables in respective ports.
Step6
Ensure that correct type of cable has been used, especially if there are multiple PCs connected to set up a network. Specific functions require certain types of cables. For instance, special Cat5 cables are needed to connect multiple PCs to a hub/switch so they can successfully function as a network.
Step7
Ensure that the dial-up or broadband modem is connected directly to the telephone line without a caller ID box, fax machine or splitter coming in between. Note that this would be valid only in case of a dial-up connection or an ADSL broadband connection.
Step8
See if the devices show correct link lights. Device lights are an indicator of accurate connections. Different lighting patterns indicate different things. For instance, network cards usually show green light on establishing a connection. Similarly, in wireless networks, the router's wireless LAN (WLAN) light is turned on at all times even if no device is connected to it. The light typically blinks when a host communicates on another host and exchanges information. Unexpected lighting indicates a trouble. Go through user manuals to familiarize yourself on this feature and make sure the devices show desired lighting behavior.
Step9
Determine if the network card is working properly. In a network, identify the malfunctioning adapter by disabling the cards one by one. If the network is wireless, ensure the network card is also wireless and is compatible on the router. A network adapter following a wireless standard different from that of the router slows down the connection.
Step10
Check network settings to verify the IP address, MAC address, TCP/IP configuration, host/domain name and other related information.
Step11
See if correct drivers have been installed. Regularly upgrade drivers so the host uses the latest utilities that take care of several issues.
Step12
Try readjusting the location of hosts especially if it's a wireless network. Move one of the portable hosts--such as a laptop--closer to the router. If it works better, interference or low signal strength is the reason for poor Internet access. Several factors responsible for inadequate signal performance include cordless devices working within the frequency range (2.4 GHz) of a wireless network, shiny surfaces and too much distance between hosts and access points.
Step13
Adjust the wireless router antenna to get an optimum signal. Most wireless routers come on omni-directional antennae to send signals in all directions, a situation appropriate for a square-shaped network. If hosts are arranged in a linear fashion, use an antenna that sends signals only in one direction. Some portable routers have internal antenna giving more freedom to users who are on the go. Use an external antenna on such routers. Antennae on varying strengths are available, implying some are more powerful than others. See if using a more powerful antenna fixes the trouble. Aside from increasing the range of transmitted signals, the reception capacity of hosts can also be enhanced. External WiFi enabled antennae attached to laptops are now available for this purpose.
Step14
Confirm that the wireless radio button, if present on your laptop(s), is switched on if you are trying to connect wirelessly.
Step15
Check configuration settings for encryption keys.
Step16
Disable the firewall (if your firewall is enabled) temporarily and check. Some settings in your firewall may cause a trouble.

Why do capacitors fail on PC motherboard

noreply@blogger.com (Austin) — Fri, 27 Mar 2009 08:49:25 PDT

Electrolytic capacitors use a semi-liquid electrolyte inside the case to make electrical contact with the foil windings. This electrical interface is inherent in the capacitor’s ability to carry current and function as an energy storage unit for the electrical power input. When the interface between the electrolyte and the metallic foil windings begins to degrade, the electrical connection begins to fail. Heat build up is the primary cause of this degradation, which, depending on severity, can cause either short-term catastrophic failure, or long term functional degradation. The life expectancy of an electrolytic capacitor relates directly to its internal temperature. Every 10° C increase in internal temperature halves the component lifetime.

When to upgrade to upgrade your PC

noreply@blogger.com (Austin) — Thu, 22 Jan 2009 01:07:01 PST

The rule of thumb should be this: Upgrade when the cost of not upgrading exceeds the cost of upgrading. New hardware should help you work faster and more efficiently. Or maybe you need to upgrade your hardware to run new software applications that will improve productivity. If that's the case, upgrading is your best bet. Similar situations include a broken PC, one that crashes regularly, or otherwise keeps you from doing the work you need to do. Clearly, in each of these cases, it will cost you more to put off the upgrade than to go ahead with it.

If you've crunched the numbers and find you really do need to upgrade, don't rush out to buy the coolest, fastest, priciest computer on the lot. The best way to put off the inevitable obsolescence of your next computer is to make sure it meets all your business needs.

Take a look, not only at your current computing needs, but also at what your future requirements might be. Will you need a full-featured database program in the future? Will you run memory-hogging graphics programs or other special applications? Doing a little research at this stage may just save you a lot of money down the road.

Monitor Color problems

noreply@blogger.com (Austin) — Fri, 16 Jan 2009 20:50:40 PST

If you have problems with monitor colors, then the most propable reason for color problems are the monitor settings and RGB signal connections.
* If you have one color totally missing, then check the connection of that color signal. There might be a bad connection or short circuit in the cable. If you have made a special cable yourself, check that you have wires all the wires corectly, because a wrongly connected cable can cause also this problem.
* If one color is much brigher that other colors there might be somethign wrong in the monitor settings for that color. Check also that the color input is properly terminated (75 ohm termination is the industry standard for analogue RGB signals, but in some monitors this can be disconnected which is not what you want to do). If you have accidentally removed the termination, the voltage in this line will be higher than it shoudl be (typically around two times what is needed).
* If you are sending black image to the monitorm but the picture is not black, then there is somethign definatély wrong in the monitor adjustments or you have connected one of RGB lines to some entirely wrong pin.

Troubleshooting with Cable Testers

noreply@blogger.com (Austin) — Sun, 04 Jan 2009 23:46:21 PST

The most common hardware related compute networking problem is the bad cabling and RJ-45 connectors. There are a number of devices, designed for testing the network communication cabling. These devices include continuity tester, time domain reflectometer and cabling testers. Data cabling testers are designed to perform a number of different types of tests on the UTP/STP and coaxial cables. The master end of the cable tester is attached to one end of the cable and the load unit of the cable tester is attached to the other end of the cable. The master unit sends the signals through the cable and reads them from the load unit. When testing the cables, these devices normally detect the problems such as crossed-over wiring, broken wires, short connections and the cable connections that are improperly impaired.
