I have a (ATI) ASUS EAH4850/HTDI/512M Radeon video card. Everything worked fine for 6 months. Then I get the ati2dvag error after running a game. And it only works in safe mode. So I try 3 different drivers with no luck. I get errors ranging from shutdowns, no signal to the monitor, and graphical anomalies. The drivers I tried were Omega, most recent from ati's website, and the original on the cd that came with it. I run windows XP. Right now it works fine with no drivers installed except for the fact I can't play any games.
