Screen Flickering Problems

[Enigma65]

I've just started getting back into the game after some time off. Have not played the game on my new system until recenlty but have noticed when attempting to play that I get a very annoying "screen flicker" problem.

I'm just starting to gather information regarding what the cause may possibly be.

I have the game's graphics settings set for the highest resolution. I'm using a Nvidia GeForce 6800 with 256MB. System is a Dell XPS gaming system with processor at 3.6Ghz.

Monitor is a Dell 2100 flat panel display, refresh rate at 75. I'm using the latest Nvidia drivers 77.77.

I have tried setting different refresh rates (lower), I have gone back to older drivers with no improvement. And yes, I use Driver Cleaner when getting rid of old drivers.

All my other games run flawlessly. This is the only one seeming to have problems.

Does anyone out there have any idea what the heck could be causing this screen flicker?

Any help and suggestions would be most appreciated.
