Every 4-5 hours my computer will just shut off, almost as if the power went out in my house. No BSOD or error message, my CPU and GPU temperatures are perfectly fine, it has only happened so far while playing games (non intensive ones at that). I'm thinking since I have a no-name generic 650w PSU that it could be dying on me, but I figured if it was wouldn't it just die altogether no allowing me to even reboot? I've had a dead PSU before and I was not able to turn my system back on.

Any ideas as to what might be the issue or what I should look into?

Specs: i5-3750k, GTX 770, 8g DDR3, 650w PSU, MSI Z68-G43.
