The stop error screen or bug check screen commonly called the blue screen of death (also known as a BSoD, bluescreen, or "blue screen of doom.


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 Outdated, incorrect or corrupt drivers can cause the system to encounter a STOP error, resulting in the BSOD.
Often, if you're lucky, the problem will resolve itself with a simple reboot and you may never have to worry about it again. More typically though, the BSOD is a harbinger of trouble and you may find yourself faced with another and another until you throw up your hands in frustration... but all is not lost.

So the easiest way to try and fix a blue screen error is to reinstall and update your system's device drivers. This is if you are able to boot into safe mode (Press and hold the F8 key during boot up). 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. There is a neat program on the net that can fix this problem, it's called DriverFinder, you can get it here.

If this doesn't work or you can't think or find the corrupt driver you could use System Restore (If it is enabled) to go back to a time where you didn't get the error. To use the system restore utility, go to 'start/all programs/accessories/system tools/system restore.


Sometimes though the blue Screen of death can be caused by faulty or loose rame cards. Check that your RAM modules are inserted correctly and arn't clogged with dust.

press "F8" while statrting , and then select "safe mode"

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.

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.
• Driver rollback - if you have recently updated a driver, you can use the driver rollback to revert back to the previous driver version.

List of STOP Errors Causing BSOD:

• Stop 0×00000003 UNSYNCHRONIZED_ACCESS
• Stop 0x0000000A IRQL_NOT_LESS_OR_EQUAL
• Stop 0x0000001E KMODE_EXCEPTION_NOT_HANDLED
• Stop 0×00000023 FAT_FILE_SYSTEM
• Stop 0×00000024 NTFS_FILE_SYSTEM
• Stop 0x0000002E DATA_BUS_ERROR
• Stop 0x0000003F NO_MORE_SYSTEM_PTES
• Stop 0×00000044 MULTIPLE_IRP_COMPLETE_REQUESTS

Here are 2 solutions:
Solution #1 Scan your registry for errors.
A Registry Cleaner scans your computer for errors in your PC's registry. Your computer's registry contains information about your Windows XP operating system, including driver, printer, software information. Over time, your computer's registry may start to contain obsolete data. A corrupt registry will easily slow down the speed of your computer because applications and drivers are loaded even though they're not in use. Fixing your registry of errors will not only prevent the Windows XP Blue Screen Of Death, it'll allow your computer to boot faster, open up multiple folders quicker. A listing of registry cleaners can be found here.
Solution #2 Process of Elimination
When the CPU calls certain functions from the RAM, or Random Access Memory, and the data rests in a faulty section of the RAM, this will cause the blue screen to appear. I recall a time whenever my computer booted up and started loading the Norton Anti Virus program, the blue screen error message would appear. This happens because the CPU is accessing data from faulty locations within the RAM when loading the anti virus software.
This method involves having 2 sticks of RAM. Remove 1 stick of RAM and wait to see if the blue screen surfaces, do the same for the other.
Through process of elimination, you'll find the cause of the Windows XP blue screen of death error.
Because getting into the hardware can be a little techy for computer hardware "adverse" readers, a simple 2 step plan is to first clear your PC of any registry errors. Then if the blue screen of death goes away, we would have saved ourselves the trouble of having to open up the PC casing and touching the hardware components

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.

In which step you r getting BSOD, in text mode setup or
setup after reboot (GUI MODE)

Boot into safe mode by pressing F8 about 10 times during the post screen. Then completely remove your video drivers. Then reboot, into windows normally, go to the Nvidia web site and download the latest graphics drivers for the video card that you have. If this does not solve your problem, then you may have bad video memory on your video card.

There must be some driver you have installed recently. Try booting in safe mode and restore your system to an earlier date.
