maybe it's the Catalyst driver. try to unstall the display driver, reboot os, then reinstall the Catalyst driver. if not success, do it again twice or more, then try to change a different version of Catalyst driver
this ruined my whole afternoon today. i really want to say "fxxk ati".
similar problems happened when Vista just released in 2006~2007, i still remember that day i installed the Catalyst 7.x after installing Vista, then OS showed bluescreen right at the installation of Catalyst driver
