Alright, when doing normal every day tasks on my computer, there is no screen corruption. However, when I decided to play counter-strike:source, there was massive screen corruption(lines and different colored boxes etc...). And I loaded up some other games and the corruption was still there. I even loaded up bridge builder(not a very graphical game at all), and there was corruption! So I don't know whats wrong, and this is only happening in games(they all run full-screen). So could this be a full-screen problem or what? And yes I have updated my ati catalyst drivers and have direct X 9.0c.
