So I'm playing black ops 2 and when i just move with the keyboard at 1920x1200 everything is fine, but when i use my mouse it starts to get glitchy and stops. I have touched nothing and the past 2 months both have been working excellent. Tried reinstalling all the catylist and drivers with the 7950 but nothings changed. What do i do, please help!! its looking like all the games in general i play, do a stop/glitchy thing when i move the mouse, why is this!!!???
