Twice this afternoon, my wife’s computer has suddenly, without warning, shut itself off. My wife was not doing anything unusual on the computer, just searching something on the internet. After she turned it on right after getting home from work, it stayed on about 2 or 3 hrs, then shut off. After she rebooted, it stayed on 20 or 30 minutes then shut off again.
The computer is a Compaq running WinXP SP2.
We know it wasn’t a brownout in either case because nothing else flickered in the house, and the second time it happened, my computer was on and didn’t shut off. What else could cause this? My guess is the puter itself is too hot, but the air around it is no warmer than the rest of the room (which is about 85 deg F). Could it still be that, or does anyone have any other suggestions?
