Hi there,
I'm experiencing some issues with my HD4870X2: after a system crash while playing a game I'm not able to run games in full screen mode.
After a clean Windows 7 64 bit install and a CCC clean install the problem still making me getting mad.
The Italian AMD customer support just told me to do the same thing that I've tried for a week. (i.e.: clean windows install, clean driver install after a driver sweep run etc)
The strange thing is that every game booted in full screen will crash at the main menu with a static image, but after a ctrl+alt+canc i can hear the game running :\
If i launch ArmA 2 in window mode and i can run it in a window large as my 24" monitor with very high graphic settings. Same with Left4dead2 via steam.
unfortunately lot of games on steam wont start in window mode with the "-window/-windowed" commands
At least, sometimes if I don't reboot the system, I'll get those messages.
