I have a newly built Gaming PC (Maybe 4 months old) that will randomly shut off. It doesn't need to be under any particular load or high temp. It will shut off while booting up a game or browsing the internet. I have CPU and GPU temps displaying on my LCD and they never go over 80 Degrees.

I have tried playing around and lessening graphics settings but that seams like my PC shouldn't need to do that. I have undone and reattached all the cables. I have reseated the GPU and RAM.

Is there a diagnostic tool that will give me more specifics on the cause of the failure? Is it just the PSU is too small?
