So about 2 days ago I started getting this random reboot thing with my PC. It happened 6 times on Friday and 2 times yesterday and today while gaming. I've checked my temperatures and they are all good. I ran memtest on my ram and that was also good. Could it be the power supply, or the power strip that is connected to the wall? I'm so lost on what it could actually be.

System:
OS- Windows 7 64 bit
Storage- Kingston Hyper X 3k
CPU- i7 3770k
Cooling- Corsair H100
PSU- Corsair HX 750
Motherboard- Asus Sabertooth Z77
RAM- Corsair Vengeance 2x 4GB DDR3
Graphics: EVGA GTX 670 2GB

That is usually the result of a faulty or too small PSU. Your PSU is high quality and big enough for most any card or even dual cards, so quality and size should not be an issue. Still could be faulty, I guess. The MB could also be at fault. But check your 24 pin and 4/8 pin MB power connectors to be sure they are all the way in. They have to clip over the locking latch or there is a possibility of them backing out with temp changes. Same with the other system connections that have locking latches.

And you may want to try running the PSU plugged directly into a receptacle rather than a power strip just to eliminate that as a possibility.

Yeah I just made sure the connectors are all in tightly. I meant to add that the Power Supply had some coil whining in the past and then it stopped. I noticed it doing it recently and much louder.

I've got my fingers crossed for you. If the card was pretty dirty, the rest of the case and components were probably equally in need of cleaning. Hope you cleaned it all good.

Well it was fine for a while and it did it again. I'm going to clean the entire PC and I'm replacing the Power Supply and Graphics card.
