Blue Screen Errors

Blue screen errors, or blue screen of death (BSOD) errors, are the most severe errors Windows can encounter. Since Windows can not recover from this kernel level error, a blue screen is displayed with the error details. The error details contain a STOP error code, which indicates the type of error.


There are a lot of possible causes for blue screen errors, but most of them relate to the computer hardware. The cause of a BSOD error can be a temperature problem, a timing error, a resource conflict, hardware failure, a corrupt registry, a virus or simply a device incompatibility or driver error.

How to analyze blue screen errors

The first thing to do to analyze a blue screen error is to check the meaning of the STOP error code. You need to stop Windows from rebooting when a STOP error is encountered. Once the blue screen of death is shown, you can check the meaning of the STOP error code. Together with the filename of the driver or module, this will give an indication of the error cause.

Another option to analyze the cause of the blue screen error is to look at the Windows system event log or to debug the memory dump (minidump) that Windows created when the error occurred. The event log can be viewed using the event viewer. Right-click Computer in the Start menu, and then select Manage. In the Computer Management window select Event Viewer. The information in the event log can be of great help to isolate the cause of the blue screen error.

Reading the minidump requires a bit more technical knowledge, but Microsoft has tools to read the minidump.
Blue Screen Of Death

The most common cause of blue screen errors

In reality, the most common cause of blue screen errors is a device driver problem. Outdated, incorrect or corrupt drivers can cause the system to encounter a STOP error, resulting in the BSOD.
So the easiest way to try and fix a blue screen error is to reinstall and update your system’s device drivers. This will ensure that all driver bugs are fixed and that all hardware has the correct driver.

If you know which device caused the error, you can update or reinstall that driver first. The file name in the blue screen of death can help identify the driver. Look for a file with the .SYS extension and search for that file name.

If you do not have the drivers for all devices, or are not comfortable updating your PC’s drivers manually, you can use a driver update tool to find, download and update all device drivers for you. Such tools will accurately identify your computer hardware, including any device causing an error, and automatically install the latest drivers for it.

In most cases updating or reinstalling drivers will solve your blue screen errors.

Other causes of blue screen errors

However, if updating device drivers does not fix the blue screen error, there are a number of additional things to try:
  • Load the default BIOS values – resource conflicts and timing issues can be caused by incorrect BIOS settings.
  • Update the BIOS – especially after adding new hardware or installing a Windows service pack this can help fix issues.
  • Update Windows – missing updates, including service packs can be a source of stop errors.
  • Check your system – run a virus scan and spyware scan after updating your definition files.
  • Run a memory test to check your computer’s RAM. Memory faults can easily cause blue screen errors, so see if your RAM is error free. Vista and Windows have a built-in option to test the memory, for XP you can use a program called memtest86.
  • Driver rollback – if you have recently updated a driver, you can use the driver rollback to revert back to the previous driver version.

Power Supply

POWER SUPPLY >>> PSU
The power supply is the componet at the rear of the PC that the powr cord plugs into. The inside consists on a numerous wires that plug into the motherboard and other devices, such as the hard disk drive, optical drives, floppies and even video cards. The power supply will normally either work or not work. This article will show you how to determine if the power supply is the cause of your computer problems.



The power supply can partially fail, completely fail, or even fail intermittently. The PSU can cause a myriad of problems and can frustrate computer users who are not use to dealing with this temperamental component. This tutorial will help you diagnose problems with the power supply to determine if it is time to replace the unit. Links to the tools we talk about can be found on this page.

To begin, is the power supply working? Just because the computer isn’t powering up, doesn’t mean the power supply isn’t doing its job. Is the fan on the back spinning?

When troubleshooting power supply issues, you first make sure you have the correct voltage set on the rear of the unit. You should see a red switch that can be set to 115V or 230V. Depending on the country you live, this switch will need to be set appropriately. For instance, the Unites States uses 115V. Secondly, make sure you are not plugging into a power strip. Power strips can fail, so be sure to try plugging the power cable directly into a working, properly grounded wall outlet.

If you’ve been working inside the case, check the thin power wires running from the front of the case to the motherboard. These generally plug into the motherboard at the lower right of the motherboard and may be labeled something like “power sw” or “pw switch.” If this wire has popped off, the PSU will not work. To test the switch, you can remove the “power sw” wire and short the pins by touching a flathead screwdrive to the two pins. If the switch is bad, the computer should power up right away. There is also the main motherboard connector, which is the long 20 pin connector. Make sure this is properly secured. Some graphics cards or motherboards also require an addition 4-pin wire connector. If you motherboard requires it, be sure this is plugged in to the appropriate socket.

Use a multi-meter or stand alone power supply tester to check the PSU. To test with a multi-meter, make sure the power supply is plugged in to a power source and that the 20-pin connector is plugged into the motherboard. It’s best if you lay the case on it’s side so you can look directly down on the motherboard. Next, you’ll jam the black lead down into any of the black (ground) wires. Then you can probe each colored wire for the appropriate voltage. If voltage is seriously out of range or does not exist, then the power supply is bad. The colored wires should have the following voltages:

The pin-outs for an ATX power supply
Pin# Color Function
1 Orange +3.3V DC
2 Orange +3.3V DC
3 Black Ground
4 Red +5V DC
5 Black Ground
6 Red +5V DC
7 Black Ground
8 Gray Power OK
9 Purple +5V standby
10 Yellow +12V DC
11 Orange +3.3V DC
12 Blue -12V DC
13 Black Ground
14 Green PS-ON
15 Black Ground
16 Black Ground
17 Black Ground
18 White -5V DC
19 Red +5V DC
20 Red +5V DC

An alternative to the multi-meter is the stand-alone power supply tester. This small device plugs directly into the 20-pin connector of the power supply. It will immediately tell you if the power supply is bad. These are cheap and easy to use.

If you are not getting power, or if your system randomly reboots or develops bizarre symptoms that you cannot nail down, consider swapping in a new power supply. Spending too much time trying to diagnose a flaky power supply could become expensive, as unexpected dip in power can damage other computer parts, such as the hard drive.

Blue Screen of Death Errors

Blue Screen of Death Errors


Any frequent Windows user has encountered the big bad BSOD, short for the Blue Screen of Death. This common error will make its presence known whenever the system senses that an application, piece of hardware or device driver is experiencing issues behind the scenes. What makes this particular issue so tricky is that it can be an indicator of anything from a minor glitch to a major error that causes your system to malfunction and leave you staring at the infamous blue screen.


On rare occasions, getting rid of a blue screen error is as simple as rebooting the system. Some have been lucky enough to restart their PC and never encounter the problem again. Unfortunately, this error usually means that your system is suffering from a critical error and when this is the case, it will not go away until you address the matter.

There is no standard solution to fixing the blue screen problems, mainly because there are so many problems that can result in such an error. This could be anything from a new program you just installed to a memory stick you added to the computer. In order to eliminate this nuisance, you must first diagnosis the problem to find out what’s actually going on. By doing a little troubleshooting, you can narrow things down and actually find the culprit.

Check Software and Hardware Components

The easiest step to eliminating blue screens is uninstalling any new software or hardware recently installed on the machine. If you encountered the problem after adding on a new component, this is likely the source of your problem. This could be due to a failed installation or incompatibility issues related to the software or a driver the device needs to function.

Check Your Memory Status

Blue screen errors could also appear if you recently added more RAM to your computer. You can find out if your RAM is faulty by running a diagnostic utility. If you don’t have such a tool handy, you will have to get more hands on by opening the computer case and removing the stick of RAM you just installed. From there, you can fire up the machine to see if the blue screen still shows up. This is actually easier than it sounds, but if you don’t feel comfortable opening your computer find yourself a professional technician who won’t charge an arm and leg to do the job.

Fix the Registry

The Windows registry is one of the most common causes of the BSOD. Over time, the registry gets cluttered with invalid files and other unwanted items that can make your system unstable. A blue screen of death occurrence is the ultimate sign of instability. You can run a registry cleaner to find out if the registry is stirring up all the trouble on your PC. These programs are fairly inexpensive and have the ability to automatically detect and remove the questionable items hiding out on your PC.

Conclusion

When the blue screen of death shows up, it will be accompanied by a STOP code that gives details on what caused the problem. Be sure to jot down this information when troubleshooting to better your chances of successfully fixing the issue.
