Was planning on trading my old HD4850 to a friend. I put it in to make sure it works before I send it off. Everything was going fine. I started FurMark. A couple minutes in it decides to BSOD with pagefaultinblahblah. When it reboots artifacts galore. http://imageshack.us/g/641/1002020.jpg/ It didn't overheat, I know that for sure. Is this type of situation salvageable?
