I recently got a new computer. I installed everything on it that I needed (Xp Pro, all drivers, ect...) I also installed some games, including Doom 3. Now, I had run other games on this computer before playing Doom 3 (HL 2 for example). When I ran Doom 3 and started a new game, little black boxes appeared running vertically down the screen. I tried to change my resolution, I tried to get different drivers, but nothing I've done so far has helped to fix it.
As time passed I got other games, and on some of them noticed the same thing. Here's a list:
Doom 3 (all over)
KOTOR 2 (In the shadows of the characters)
Sims 2 (all over)
Halo (all over)
If anybody has seen this before and knows anything about it please tell me.
