oh, you you wanted 'professional' advice. hey, here's a thought. RTFM! and if that doesn't help, e-mail the 'professionals' at ATI, and see where you get. I'm sorry i posted the best advice i had, considering you needed 'professional' help. you asked for advice on it, I gave you that advice, considering that my roommate uses a Radeon 9200, and is perfectly happy with his drivers.
did you consider that you might have installed the drivers improperly? like, removed the current ones entirely, then installed the new ones? I thought that was a given, like, you would have automatically run to the 'professionals' and gotten your step-by-step instructions for safely updating your drivers.
sorry for the flame, but you know, just because it fudged up for you, doesn't mean it fudges up for everyone.
