Hi guys PC shuts off after a while of gaming and I think it's the CPU overheating, but can't be sure. I just wanted to eliminate that it might be graphics drivers. The video card seems up to date and all but the chipset nforce drivers have confused me. When I first installed some (about three weeks ago) I was given version 15.17 by the nvidia site. Now when I go to Nvidia.com and put in nforce 780i I get given 9.64, which seems to be an older version. I am wondering if anyone can advise if I might have installed improper drivers or something? Thanks, Chris
