About 4 months into having made my own computer, it began to suddenly reboot.  Okay here's the weird thing: the reboots are quite rare, about one every month, They haven't been getting worse. I checked the HDD and CPU temperatures, HDD for errors, did a memory test, exchanged the power supply, and took out the UPS, trying to find the cause. No luck. I disabled rebooting on blue screens or any other form of automatic update and reboot. The reboots are sudden and come with no warning. I don't even know where to start! A little help please? My motherboard is a Gigabyte P4 Titan.

it does it at random times or does it do it when your playing games or using the CPU allot. It might be a North bridge heat problem but im not entirely sure at the moment. you said you have a UPS what type?

Completly random. Did it in games, did it when listening to music, did it when idle at night. I've used the computer and strained it to its limit many times, I could not trigger a reboot. It only reboots "when it wants to". My UPS is a Mustek PowerMust 1000. Even with it taken out it still does the reboots. If you're concerned about CPU, like I said I already ruled out heat.

 Basically I posted this thread because of desperation, knowing I have tried checking just about all the classical causes for restarts.

 Yes I did, and ran two different operating systems on the machine too. It still did it...

 humm i really have no idea. im guessing you have done a fresh install on it then since you ran two OS's on it or did you just dual boot them?
