I just built my PC. Everything has been great. Now i'm playing games and they will randomly crash about 5-10 mins in. Black or blue screen and audio loop. Has happened on Arkham Origins, BF3, and Stronghold 3. I have played Guild Wars 2 and this does NOT happen. I checked temps and everything is normal. All drivers up-to-date. I don't know what it could be.

Asus Z87 Gryphon
16GB (8x2) mem
Asus GTX 770
Rosewill 750 psu

Anything else? Please help
