Recently installed a new motherboard and all was well unitil it randomly shut down while playing a game and then it would only turn in for enough time for the fans to make a sound before shutting down again.

Can you get into the BIOS and check the temps before it restarts? Does it even make it to the motherboards splash screen? Do you get to the windows logo?

I decided to unplug each piece of hardware individually and discovered that if I unplug my GPU the computer boots, I haven't been able to see what it boots to though as my motherboard has no monitor slots. I think that the problem is that my PSU simply doesn't have the power for my system!, even though it's 750w. Will look into getting a new PSU but please inform me ifnunthink it could be something else.
