I need help I have just go black ops 2 and pretty much every game it freezes and I can hear the sounds but i'm frozen and then I leave to my desktop screen and I can't shut it I have to wait for it to say black ops 2 has stopped working. It wont let me close it either. I have had problems in the past with battlefield 3 where at random moments it says you gpu drivers 314.?? have stopped working and have sucesfully recovered. the reason why i mentioned that is two or three times I have had this message come up on bo2 and has made me quit the game. The GPU is the Nvidia GTX 660 and the CPU is a I7 3770k I just want to know how to fix this it has anoyed me for a while now.
