My computer shut off while I was playing Diablo 3 proceeded to restart itself very quickly but the fans were running at full speed in the graphics card. After looking at the inside everything else is working fine the motherboard is working properly the only thing that isn't it seems to be the video card the fans on it are going full speed but I'm not getting any video however I can hear the computer starting up and throwing errors. Ideas? It's a GTX 760 I got like 3 to 4 years ago
