Call of Duty 2, Tech problem.

[worldpease]

Recently I aquired and installed Call Of Duty 2,
I played the entire game without any problems... but yesterday,
I installed the software for my Video Card and since then, the game
started to do wierd things, like:
-the intro (logo video clip) wont apear, just audio and black screen.
-when I get shot and the 'red cloud of blood' is suposed to apear, the screen blinks.
-when I die, instead of the blurry screen, the screen is full of big pixels.
-and the when I shot a gun, the sound isn't right anymore.

do you have any idea what could be the problem?
-thanks.

I would definately try reinstalling the driver, and make sure that you have the latest available.
