Whilst playing games my PC decided to shut down. After it shut down it would boot up for about 2 seconds and cut out. It would do this on repeat. I had this problem about a week ago and thought it was the PSU so i replaced it with a new one. Now its happening again, I read that it could be the bios so I reset it by taking out the cmos battery for about an hour and it worked...for about 2 hours then the same thing. Today it wasn't working either until I got home where it turned itself on and is now working. Any chance anyone can solve this?

Specs:
CPU: Intel Pentium G3258 3.20GHZ

Ram: Geil 4GB DDR3 PC3-12800
CPU cooler: stock
Video Card: Asus gtx 680 directcu ii
