I recently built a new PC and i've been having a strange graphical issue, when i'm running more than one application at a time (such as a youtube video and Diablo 3) which ever application I opened second will have some visual issues appear on it at times. On Diablo 3 I get two small parallel white/black lines scattered around the screen, on a youtube video I get white lines moving diagonally across the screen, on World of Warcraft I get objects that look kind of like a cracked mirror scattered around the screen, on far cry 3 there has been large red squares when I look into the distance and on League of Legends I get black squares surrounding any object I hover my mouse over. Also the issue occurs on both screens so it can't be my monitor dieing.
This issues don't always appear instantly i'll usually need to play for a bit or change a setting, like in diablo 3 change from windows mode to fullscreen although once they have appeared they will always appear instantly when running two applications until I reset. I've found that if in Diablo 3 the shadows are set to medium the issue will go away for a while but eventually it'll reappear.
I've tried everything I can think of to fix this, i've updated the BIOS,tried only one monitor, updated Windows, updated firmware on my SSD, updated my gfx card drivers, tried different graphics card driver versions, turned down the clock on my gfx card, checked temperatures and formatted my PC then tested with the bare minimum installed but the issue remains so I am lost can somebody please help?
A screenshot of what the issue looks like on Diablo 3:
Sorry that it's difficult to see, hard to upload clear images. The red circles were put there by me, i've tried to circle some of the errors so that people can see them clearer.
