My NEW BUILT PC, randomly black screens while im using it. Please help ASAP! I have a EVGA GTX 960, AMD FX 8320, CM Hyper 212 Evo, Windows 7 Home Premium 64bit, and an ASUS M5A97 Motherboard. The black screen might be permanent, because I waited 5 minutes, and it doesn't turn back on, so I have to restart my PC. Please Help!!!
