What would cause a PC to randomly restart itself? Mine has been doing that for 1-2 weeks. I think it may have something to do with the power supply but I don't know how to check. It runs fine normally, and sometimes it can run for many hours before restarting itself, yet other times it restarts itself without much time in between. We've had a number of thunderstorms, and though I have a surge protector, I wonder if something may have happened anyway. The only other thing I can think of is that maybe my computer is overheating. I do have a lopsided computer, I have a 6800 nivida graphics card, and 512mb ram (more ram is coming in the mail any day now), however, this doesn't explain why the PC restarts itself when I'm not even playing a game. It can be on its own for an hour and decide to restart itself.

I've had this happen a few times aswell. Nothing like 5 times a week..Maybe once or twice every few months.
I'd like to know what causes a PC to turn ON in the middle of the night after it's been off for a few hours. O_O | |
No, nothing. It just goes poof. Like right after I wrote the first message in this thread it went *poof*. I think at one point I may have told this PC to restart itself after a power-outage, but I don't know where the setting for that is any more.

Probably in the BIOS somewhere. My PC doesn't wake up for anything except the on button, which is just how I like it :-).

well 1 of three things come to mind.
1. sounds like it is may be overheating. (open and clean the dust out) 2. Needs a biger power supply. (did you just update somthing?) 3. The ram is not geting the power it needs, up the ram voltage in the bois slightly. | |
If it isn't already off, you may need to turn off the auto-restart that XP does on fatal errors. To do this, right-click My Computer and hit Properties, go to the Advanced tab, hit Error Reporting, and uncheck Automatically restart. This will let you see the Blue Screen of Death instead of it restarting, which may give you some clues on what's wrong.
If it's already off, I guess one or more of your pieces of hardware is failing. It could really be any of them, so your only option there is to switch them out one by one with known-good components to see which one is bad. | |
Okay, if you're running windows XP, reboots are how XP hides it's BSOD's.
Secondly, your bios may reboot your CPU if it gets too hot. Check the cooling, like the guy above me said. Third, make sure your power supply is providing enough power to all components (again, like the people above me said). If you're overclocking anything, that could be the cause. Make sure that everything is at their default operating frequencies. If everything checks out, your power supply might be crapping out on you. You could just go out and buy a new one at the local computer store... good ones right now sell for about $20 to $60. | |
"60 seconds until the computer restarts" or something.
