Morning, I did a program upgrade on a Dell M6600 with a M8900 and the video display is now corrupted. I did the clean uninstall and reinstalled an older version of the amd program and no love. The system now has the blank screen when running the AMD software. The default win system is fine and up to date. I've tried fresh installs of Win 7pro 64 and still dead system. I'm in need of the proper files to regain the system.
