1. Get the error number – Most BSOD errors list a numeric error code that will help you research the problem online. Look up the number online using a different computer and see if Microsoft or tech forum has information about the error. If you find actionable information about your BSOD error code, take corrective action.
2. Reboot – If you have ever phoned technical support, you know that this is a favorite solution for many “technicians” who have no idea about how to solve a problem. Go ahead and reboot your computer: today might be your lucky day.
3. Look for triggers – If you’re fortunate enough to be able to restart your computer, pay attention to what happens before the BSOD recurs. This can give you clues as to the cause of the error. For example, if you get the Blue Screen of Death when you start your scanner software, you can try disconnecting your scanner.
4. Boot into safe mode – If your BSOD allows you to boot, try starting the computer in safe mode. This will allow you to eliminate unnecessary drivers and programs that could be causing the BSOD problem.
5. Random BSOD crashes could be caused by heat – If you can, open your computer, blow out the dust, from off your components and make sure your CPU and case fans are working.
6. Check and repair your registry – Some experts seem to think that registry errors can produce BSOD problems. If your computer will boot, download and run a registry repair tool or follow registry repair instructions from Microsoft.
7. Check your memory – Memory is a common culprit of Blue Screen of Death errors, and it is often fairly easy to replace, so do so. Some local computer shops will let you try replacement memory before making you pay for it to see if it solves your problem. If it does, buy it. If not, just give it back. While you are there, see if they have any additional suggestions for you.
8. Try uninstalling programs or new hardware – Often BSOD results from recent changes to your system. If you installed new software or hardware, try uninstalling it. This will help determine whether your Blue Screen of Death problem was introduced by those changes. Some of the error messages may be indicative of hardware or device driver issues such as IRQL_NOT_LESS_OR_EQUAL, or KMODE_EXCEPTION_NOT_HANDLED, while errors such as DIVIDE_BY_ZERO_ERROR often result from a software bug.
9. Unmountable Boot Volume BSOD errors – If you’re getting these errors you may have a corrupt boot.ini file or a hardware defect on your controller or drive. You can try booting on your Windows disk and reinstalling, although this error may require replacement hardware. You can also go into your system BIO settings and turn off UDMA access to see if that helps you avoid the BSOD.
10. Repair Disk corruption – BSOD errors often occur when a corrupt disk is attached to your system. Remove secondary and external drives to see if your computer will boot without them. You can also try using a boot disk to start your computer and then run chkdsk /f /r to repair.
One more thing when trying to stop the Blue Screen of death: fixing the 10 most common causes may not resolve your problem. The BSOD usually leaves behind memory dump files that may contain clues about the error. A free program called Blue Screen View will scan those dumped files and offer insight into their causes.
