Did it all, even was on the line with ATI. Their is no driver problems. Before the ATI I was using a g3. Solid as a rock. But since installing AH2 the system is unstable. You know, I am not the only one that has developed problems since this install. AH2 uses direct X more now then in the past with T&L and such. Their is some correlation between that (DX) and the problems with AH2 since I seem to get a DDHELP caused an invalid page fault in module (unknown) message when it crashes (usually) I have removed DX and reinstalled, It shows that all is good. My drivers are on correctly. I cannot find any conflicts that are causint this problem. But, I do believe its something in this game thats doing it. What I have no idea. I was playing Far Cry last night which is known to tax a system, with all turned up very high and it did not crash, yet playing AH2 usually crashes. I have spent alot of time analyzing this problem and cannot find an answer
