JonBodner,
It's been awhile since I played the Baldur's Gate series. Which version of Baldur's Gate 2 are you running? Is this the classic version or the new "Enhanced Edition"? If it's the classic version, I recall you can switch between DirectDraw and OpenGL for the render engine. There should be a link to a configuration program in the start menu. Can you check the game options, note which version you have selected, and see if toggling the option helps? I think you need to skip the "test" option (the part that shows the colored squares). Also there is a patch available, Google for it.
