Running into a problem.

Trying to launch a game, after about 20 seconds of the launch screen, the program stops responding. It dumps an error file:

I've turned DEP off via command prompt, I'm running as an administrator.

Not having a good day.

Windows 7 freshly installed. Am I missing a driver update or a windows update or something?
