A little problem started pestering me recently and I couldn't figure out the cause. Whenever I start playing a video file regardless of format or the player that is used this happens http://tinypic.com/r/11hdmi0/5 , it doesn't happen with games or stress tests and as long as I don't start watching a video, the PC could run fine for days.Weird thing is it only occurs on the main monitor and the OS doesn't crash, I can still do stuff on other screens. I can make the display operational again by either rebooting or turning it off with hotkeys and turning it back on. I have tried taking the gpu out, pluggin it back in, updated catalyst to 13.9, then to latest 13.11 beta, tried a different DVI cable, even tried using a displayport cable thinking the output is damaged but, the problem persists. Specs in the sig.
