Hi guys, I was recommended to these forums for this particular issue...So in the following video you can see that when crossfire mode is enabled on my laptop, when I play any game (I use Natural Selection 2 and Diablo 3 in vid) you'll notice the white flashing lines. Without crossfire enabled this is not an issue. I opened this laptop 2 days ago and since I've owned it the problem persists. Dell's tech support remotely updated all of my drivers and after spending an hour and a half on the phone they failed to provide me with a solution other than sending a tech over with a replacement part. If anyone can help me out with a hopefully quick and easy fix that`d be great. This issue is with any game I boot.
