Is it my PSU?

Thanks for the response, i just went to retrieve the BSOD dumps and when i powered on my PC the screen would come on and say "Entering power saving mode" and wouldn't boot properly. I am confused as to whether it is overheating because of how it can run a game like BF3 for hours fine and other times freeze right after booting, or most recently, wont boot at all. The same thing applies to it being a PSU Issue.
