Everything seems to work fine except one thing... In Call of Duty 2 (after the intro movies which work fine) the main menu is just a black screen but the music is playing and I can select options at the menu. Serious Sam 2 starts at a black scren as well. In Civilization 4, at the main menu the background (A spinning earth globe) works fine but the small window with buttons in it is invisible (I can still press the buttons with my mouse as if the window still was there). Doom 3, however, works perfectly fine.
