Lately I've been getting this message a lot during various games, and I don't know why. The game will freeze up on me, this message will show up, and the screen will go black, and then either the game will start running again in a few seconds, or it will shut down entirely. Sometimes (see screenshot) happens too, and sometimes it will just go away after 10 seconds or so, but usually I'll have to restart my computer. I have a Sapphire AMD Radeon HD 6950 Dirt3 Edition flashed to 6970 and OC'd to 900/1375. How can I make this stop happening? Any advice or instruction would be appreciated.
