Was their a bug on the Beta ATI drivers that fixed doom3 performance that caused the video card to shut off and freeze the computer on athlon64 boards ?

ive just been here trying to find what the hell is making my monitor go into standby and the pc freezes while ime doing anything to do with browsing the net or using outlook express... anything with text involved .. small graphics , n so on.

ive just updated and so far ive been simulating the usual that made it crash and it hasn't.. but i cant rest until someone else can tell me if they had anything similar on a atlhon64 computer when they tried those beta doom3 ati drivers.

please jog your memory i really need to hear even a uncertain answer here.
its getting desperate noexpression.gif .. i just spent alot of money to buy this hardware yesterday.
