Windows 7 - ATI 11.12 upgrade fail

Hello,

After updating new catalyst 11.12 my screen goes black during the shutdown/restart mode. The computer still runs and I have to hold shutdown button to restart then it'll come up. It only happens when you shutdown/restart. I'm running Win 7 64 bit Home Premium so I'm wondering if there's a windows problem. Any help would be appreciated thank you.

Alienware M17
Win 7 64 bit HP
8gb DDR3
ATI Radeon Mobility 4870

sounds like a compatibility issue. Run driver sweep in safe mode and uninstall the current ATI driver and then download and install a previous version.

YOu wont see much benifit from the 11.12 update, its mainly addressing multi gpu setups for scyrim and bf3. not really aimed at laptops.

Driver sweep sounds like a good idea. I've ran CCleaner, went into regedit and deleted everything Catalyst etc. installed previous drivers just to check. The weird thing is I did a clean install with disc provided by Alienware (Dell) and it wouldn't work. Let's see what happens. Thanks man.
