I have been having this problem for some time now, easily over 3 weeks. I have tried multiple fixes for this, including uninstalling my GPU driver and reinstalling it, reverting it back to a previous update, and then reupdating it.
The error occurs normally after 2/3 hours. (I play LoL a lot). So after 2/3 games the 3rd/4th game will crash upon launch. To counter this, I have come accustom to restarting my computer after each game of LoL, just to be safe. However the error does still occur on other games, such as WoW.
I'm really not sure what to make of this error, I can live without finding a fix, but it would make my life a hell of a lot easier of there was one.
Images of the error message for both WoW and LoL, followed by a dxdiag.
Any advice is appreciated.
