My current PC is about 1 to 1 1/2 years old, running XP with all updates. It was humming along fine until about 6 months ago. The computer will shut down on its own. No warning other than it freezes up for about 3 seconds before doing so. It seems to happen only when it is under a load, such as playing a game or running the virus checker.
Things we have tried:
Running a virus scan (when it gets all the way thru the scan, it never comes up with anything).
Switching out the power supply (worked better for about 3 days, then back to the problem)
Plugging it into a different outlet (no change)
Reloading the operating system (this will usually work for about a year, then the problem comes back)
Changing out the RAM (no change)
Getting a new computer (fixed the problem for almost 2 years, then it started happening with the new one)
What really gets me is that it is the same exact problem with two differnt computers. On the old computer we reloaded XP at least two times, and each time it fixed the problem for shorter periods of time until we finally threw in the towel and got a new system. Heat does not seem to be the problem.
It is driving me nuts! My husband wants to reload XP onto this one (it will be the 2nd time for this computer), but I know now that it is a temporary fix. I'd really like to know what the problem is so that can be fixed once and for all. I know someone out there knows the answer and I hope that someone is here.
I don't know all the gritty details like specs, but if you really need to know that stuff I'm sure my husband can figure that out.
