ATI Display driver crash

[Blathian]

I installed Windows 7 64 on my new imac 27" through bootcamp 3.0. Installation went smooth, but now im getting a yellow dot pattern , then screen goes black for a second then message" ATI family stopped working" kinda message. (i can get exact verbage if it helps).
So it does this alot when im just cruizing around windows 7, BUT no issues at all when playing my PC games. WEIRD!!
Anyways looking for some advice, heard using 3.1 bootcamp update gives you another wired display issue of not being in 32bit or something. And i dont want to just start messing with drivers and mess games up.
WHY CANT THINS THIS JUST RUN SMOOTH LIKE THE MAC SIDE!!!
thanks

Hi, same problem unfortunately. Seems pretty common with the 27" iMacs and bootcamp 3.0. You can load up bootcamp 3.1 which has newer Ati drivers that don't crash, but there is a bug in them that makes your display seem like it is set to 16bit colour.

Apple haven't provided a functional Ati Driver for windows yet on the new iMacs.

Why do you care if you're using a driver from Apple? Just go to ATI and install the latest Catalyst driver for Windows 7. I did that on day 1 and haven't had a single graphical hiccup in Windows 7 x64.

Did you install radeon drivers or mobility radeon drivers?

I think they're the same (at least as far as the 4xxx series is concerned), but if they are different I believe I went with the mobility drivers.

ATi's newer drivers seem to crash A LOT.

I get a "ATi Display Driver was unresponsive" every time I come out of sleep. Sometimes when I close a game too.
