I have had the same error for 2 weeks now and its doing my head in. Ive tried so many different quick fixes as shown on several forums but still no joy I'm hopeing its not my GFX card as i can't afford £200 + to buy a replacement. It was running Fallout New Vegas perfectly and then I went on one day and it wont move past this error. The GFX cards have the latest drivers etc and Ive uninstalled and reinstalled the card itself but it states in device manager that theres a problem with the device.... Anybody else had similar issues please talk me through it as I'm fredders with it now.
