I keep getting this error while watching videos on YouTube. It usually happens a few seconds after a "The display driver has stopped working and has been recovered" error message. My card is at stock speeds (Other than a factory overclock of a whopping 10MHz) and it's happened on multiple driver versions. My Card is a DirectCU II 6950 1GB. I've got an i5 2500k overclocked to 4.4GHz @ 1.3v too.
