PC Keeps Restarting: What Do I Do Next?

[MrControversial]

I reformatted. Reformatted again. Ran Memtest. Ran SuperPi. The rails on the PSU look healthy. What do I do next?

The only time things work is when I uninstall all video, LAN and mobo drivers. However, all of that is integrated into the motherboard.

Is there a utility that I can download to stress the motherboard so that I can reproduce the problem. I could be working for 4 hours straight with no problem and the sucker just restarts out of the blue. The only thing I can think of is a bad motherboard.

Come on, AT, don't let me down.

According to your post, you are oc'ing. So does the system reboots when it's not oc'ed? If it doesn't, then it could be that the cpu is overheating? have reached it's max stability based on temp and voltages or the PSU can barely support the power requirement. Try lowering the oc until you reached a very stable system. Also the rams could cause the rebooting.

On my old PC it would do this when the second ram stick needed to be reinserted. It did it about once every six months. The first time it started doing it, I was thinking PS, but a new one did nothing.

But this sounds like when I tried OC'ing my present PC a little too high. It would randomly reboot when trying to play any game that stressed it, Far Cry was the worst, but Generals, and a couple others were pretty unstable too.

you may have unstable overclock, try running at stock/lower speeds and see if the problem goes away

Have you tried turning off automatic restarts on System Properties?
