Windows restart.

Every once in a while, usually once or twice a day, my desktop shutsdown and restarts itself. Any way to fix this? It's getting very annoying.

The whole computer shuts down or windows explorer?

XP is set to reboot when theres a system failure, this can be turned off.
Start > controll panel > system > Advanced > startup and recovery settings.

Youl need to provide more info about when this happens, Things you are doing when this happens for people to have a better idea about the cause. Theres no single reason why this would happen and the turning off "reboot on system failure" is by no means a fix.

I just noticed your thread about your clicking computer.
These two issues could possibly be connected.

Like meman said, more info would be helpful. This used to happen to me when I would try to access Word or Excel documents on an old Novell 5.1 Network share. I finally got too irritated and switched back to Win2K Pro from XP SP1 and never had a problem again. I still to this day don't know the root cause though.

The whole computer shuts down. This started happning to me a few days ago, never before that. And it doesn't really seem to be what I'm using. I've used multiple things I've used in the past tons of times and only now does the computer randomly shut down.

Is it actually shutting down, as in logging you off, and powering down the system, or is it just shutting off suddenly like the power went out?

Shutting down like the power went off.

how old is the PC? posibly a bad power supply?

Is the CPU fan spinning normally? slowly? making a noise? If the CPU overheats it could shutdown on it's own, but usually starts giving you blue screen abends first.

Do you see a message from windows saying 'windows is shutting down' or is it fast like when you hit your reset button?

I was also thinking power supply that would probally be the first thing to check, you can get a power supply tester for $20 or so, just check around if you have a local computer store (not Best Buy or Circuit City but a REAL computer store) they should have them.

It shuts down like right when you pull the cord out of the power outlet. Should I get a power supply tester from Staples?

Update: Now that I've payed additional attention to it, it mainly only shuts down while I play a video game. Now does anyone know if I can fix it?

My best guess is you are having a problem with your video card or the driver. My second best guess would be that you are getting a paging error in memory. The problem with troubleshooting is, that kind of shut down gives no opportunity for your event log to write an entry making it difficult to troubleshoot.

There is another possibility though, and now that I think about it, even more likely than the first two I mentioned. Are you overclocking your processor? Your computer will respond exactly like this if your processor overheats, and I suspect this is not an uncommon problem with gamers that overclock. (Unless they've taken cautionary steps for cooling). Even if you are not overclocking, the game still may be working your processor to a slow death.

btw -- what game are you playing?

Although this list is not all-inclusive, it will give you a reference to see if there are any known conflicts with the game and XP

XP Software compatability

I play World of Warcraft, MMORPG. I just updated my drivers. Should I just turn my computer off after I've gotten everything done? (Usually, I just leave it on.)

Well -- A reboot may or may not help. Some program installs need it, some don't

If you want, I can turn the "Restart on error" Off and tell you what it says?

As in, when the blue screen pops up when I get the error, I'll tell you what it says.
