A couple of months ago my pc started to crash while playing a game(gpu fans spin really fast and no signal to the monitor). So i Cleaned my Graphics card with a Brush. But when i start game the Gpu fans spins really fast and my game is really slow. Like F1 2012 i had 60fps(easily) on highest settings as possible. and now 32fps on lowest setting as possible. i cleaned all the dust. anyone has an idea?
