Ok so i just upgraded from 8600gt to gt 220 installed everything workes fine, when i enter a game its really smooth no problems but then after bout 6 minutes my screen starts flickering, it kinda shakes messes up texts etc when i go back to desktop it slowly startes to dissapear. but sometimes i can play for an hour and that shaking screen flickering dissapears O.o but its really annoying i really want to fix for it.
I know its not the GPU temperature because its 40 c at desktop and 60 when playing games.
Things i did
Uninstalled, reinstalled drivers
Unplugged video card then put it back in
That's basically it, its probably my monitor or the video card
Thanks for any help
