I have restarted my laptop, same thing happens. Full screen/windowed mode doesn't make a difference.

Edit: Intel HD 3000 integrated graphics. Not sure if it's the culprit. I can't see any cinematics before launching the game; when I select 'Baldur's Gate' in the main menu, I see some horizontal bar on the screen, some rough sound and that doesn't go until I push some buttons. Then I get to the main menu of Baldur's Gate. You know the rest of the story.
