Atomic, should I try starting up the game in Safe Mode, that way I know if it's a background-app interfering? And I do not have either of those apps you stated in your post. My system was able to play these games long before this error, it just started happening randomly.. They are all current games, like Rainbow 6 vegas 2, C&C Generals, Battlefield 2, etc.
The CD's are not scratched, the drive came with the XPS so I don't think it's dirt ****** but it's certainly not top of the line (LOL it's DELL!), and my RAM is fine.. My PC is mostly clean, I have a lot of stuff on it, but it's not over-flowing, so I should be fine with my gaming..
Again, Do you suggest I try runnning a game in safe mode??
