I recently upgraded to a Radeon 7870 (PowerColor version). I plugged it in, and as I am browsing the internet or using Windows Explorer, I get these dancing pixels. Along with that, when I play a game (I tried it with Deus Ex: Human Revolution and TF2) I get these weird flashes across my screen. Now the games run perfectly fine, but they are unplayable with the flashing. I have tried updating my drivers, to no success. Any help on this subject would be much appreciated.
