Ok, so I've been playing on the Xbox and i wanted to play on the PC. So I Installed Skyrim, Started it, Watched the Bethesda sign, and a giant exclamation mark with a red box around it took the place of the Skyrim Symbol, I ignored it and Selected new game and the game crashed. Can anyone tell me what to do? I think it might be the graphics card.

Please post a dxdiag in spoiler tags.
