AMD 5870, 2 screens, using SSD for windows and program files. All was going well with a driver that was ? age from an older less-able ATI card. Updated catalyst driver today and nothing but a problem since. The screen became pixelated with random colored blocks and green pixel noise. Tried a 1 year old driver with no difference. No problem with display with driver removed. Any suggestions?
Thanks to treefrog07....used DriveSweeper 3.2 (free download but I'm going to give them some Paypal); removed all traces of amd priorware and installed the 12 beta CCC and Voila!! it came to life!
Thanks to the forum; thought I had a bad board

Be sure to completely uninstall your previous driver, with DriverSweeper, for example. Then visit AMD's driver site here, and download and install the latest drivers for your 5870 and operating system.
