Self Built Computer Shuts Down

[BookOfNostradamus]

Hey, I have a recently self built computer that has randomly shut down twice. It does not go to the blue screen of death, it simply goes dark and shuts off, then turns itself back on. It is running Windows 8, but I can not find any crash reports. If you could figure out how to fix this, or even why it's happening, that would be great. Thanks!

Update: It happened a third time

Need more information about the computer itself.

CPU, GPU and Power supply at least please.

Rough guess is powersupply but without more info it's really really rough.
