I have a Radeon 280x and am having an issue. Randomly, it seems, the screen will flicker and glitch. Sometimes it will crash the PC, sometimes it will go to a black screen. I have installed this on 2 different PC's with same effect. I have used 4 different drivers, including the most recent released and beta, and currently 13.12 which is what I have found to be the most stable. It doesn't happen in games, mainly on the desktop or in a browser screen. Any help would be greatly appreciated. I have tried to narrow down what causes it, and have been unable to so far. I am not running Raptr and it is completely uninstalled. I have Windows 8.1 on one PC and Windows 7 on the other. Both have same issue.
