I went to play Left 4 Dead on the 1.1 prerelease drivers
and it crashed and locked up my system when loading a level. Since then, when ever i restart the computer my screen goes black at the login screen, i can log in but the screen stays black. The display works fine in safe mode. I deleted the video driver
and then i can get back into windows, but when ever i reload the old 1.1 driver from windows update or the the latest driver from the ati website it goes back to a black screen when windows gets to the login screen.
Any help would be helpful.
