I know there have been other requests for help, but no answers yet.
I get a complete system lockup and dump from Call of Duty 5 with the message Direct3d Driver Failure. This makes me do a complete reboot each time. I've reinstalled, updated my video driver GTX 7950, and I run a 2.66 Ghz, Dual with 4 megs ram. I've reset the page file to 256megs and disabled all security to run the game.
I just recently installed the update to COD 5 and dumped that and reinstalled the whole game and the update again. Same problem.
