Having a strange problem w/ the above mentioned motherboard. It does this at stock speeds and w/ my OC. I can reboot my computer, and like 90% of the time it's fine. The other 10%, I'll hit reboot in windows, and the machine will turn off instead. I'll then hit the power button, it turns on for like 3-5 seconds, then turns back off. This results in me having to clear the CMOS to get it to POST again. After it POSTs, I'm in business again, can redo my OC, and be off to the races. WTF is going on? Everything is stable, I'm sure of that...so whats up?
