"To err is human," the old joke goes. "But to really mess things up requires a computer."
This Answer Line collection concentrates on the absolute disasters of Windows computing--the problems that threaten your PC, your career, and your peace of mind. Here's what to do when Windows throws the dreaded Blue Screen of Death your way, and how to restore your OS even if you've lost the original restore CD.
Why Does My PC Keep Dying With a Blue Screen of Death?
Gael Busson, Montreal, Quebec, Canada
What's worse than the sudden, unexpected appearance of a blue screen filled with white text? Recurring appearances of
Microsoft calls these freeze-frame moments "stop errors," but everyone else uses a much more descriptive title: The Blue Screen of Death (BSoD). They occur whenever Windows senses a problem that won't let it operate properly.
When you encounter a BSoD, there's not much you can do except mourn your lost data (whatever was in memory but not yet saved to disk), reboot your machine, and go on with your life. If you start getting them regularly, however, you have a problem that must be addressed.
The question is, what's causing the problem?
Believe it or not, BSoD screens actually contain some useful information--albeit not much. The next time your monitor and mood suddenly turn blue, grab a pen and a sheet of paper and jot these items down before rebooting:
Once you've rebooted, use your favorite Internet search engine to find pages that mention both BSoD and some of the terms that you jotted down. The statement in all caps with underlines instead of spaces will likely be useful here.
If a Web search doesn't yield helpful information, ask yourself what has changed on your PC lately. Did you add hardware or update a driver just before the problem became common?
Bad drivers often give Windows the blues. If you recently updated a driver, try reverting to an older version. Here's how:
Conversely, if you recently added new hardware to your system, installing a more recent version of the driver may fix the problem. Check the vendor's Web site to see whether there's an update.
A bad RAM module is another potential cause of BSoDs. You can test your modules easily with Memtest 86, a free program downloadable at Memtest.org. Memtest isn't a Windows program, and you must boot it
Overheating is another common culprit. Check your computer's air vents for blockage. If you have a desktop, open it and use an air canister to remove any dust you find. (If you have a laptop, check with your vendor to see whether you can clean out dust without resorting to professional intervention.)
And while your desktop is open, check the internal connections to confirm that all of them are firmly attached. A loose connection is yet another possible cause of Blue Screens of Death.
As with virtually every other major Windows problem, the fault may lie not in your hardware, but in your Registry. If you can, use System Restore to return that great compendium of necessities and problems to the state it was in on a date before the problem arose.
If all else fails, back up your data and take your PC to a professional. It's OK to admit that you can't fix some things yourself.
