Just picked up a GTX 960.. I have an I5-2400, 8GB ram, up to date bios, Corsair 650PSU 52A.. up to date Nvidia drivers.. I've taken my CMOS battery out to clear.. I've used DDU to remove all previous AMD drivers and Intel.. the problem I'm having is my screen will lose signal and or will crash and restart. Or sometimes the game application will just close.. when gaming works, it works great.. but whats going on.. my psu is more then enough power no?
