I have been experiencing a lot of freezing and colored artifacts when playing DayZ. Last time I launched DayZ, i got into a server and 3 seconds later, it froze and green artifacts starting popping up and the sound kind of starting looping. I thought at first it was video card, but I have done several tests, and played other games like Far Cry 3, on everything high, and it ran pretty smoothly, other than the fact that I have an XFX 8800 GT Alpha Dog, lol. Here is a picture of latest crash that I have received. Please and thank you.
