So I recently upgraded from a 4850 to a 5870, and randomly when playing any game this will happen:http://img88.imageshack.us/img88/2929/screenshot2i.png
I've tried both the 10.2 and 10.3 drivers, and my card isn't overheating its only at 55C when playing most games. I've had this happen in Oblivion, Global Agenda, L4d, and Tf2. I can only fix the problem by restarting my computer. So is my card the problem? Should I RMA?
My specs are:
CPU: AMD Phenom II X4 940 3.0Ghz
Memory: G.SKILL 4GB DDR2
Motherboard: MSI K9A2 Platinum AM2+
Power supply: CORSAIR CMPSU-520HX 520W
Video card: Sapphire Ati Radeon HD5870
