Hey, when i'm playing lfd2 after about 30 mins or so my entire screen blacks out, or the video is all messed up looking and the audio loops. It seems to only happen in lfd2 because i played assassin's creed 3 for hours and it never happens, chivalry, gta 4, etc. What could be the problem?
I have the latest drivers from the amd site

Is the card manually overclocked? If it is, try going back to default speeds. Any luck on L4D2 forums?
