reexamine Now, wait a bit, we are still telepathic psychics here, we will find out from a distance what kind of Windows you have, what kind of hardware you have at least video, whether you have up-to-date firewood, what patch you play on, whether you use mods or play vanilla.
If you have through Steam, then check the integrity of the files. Does not help - then reinstalling the game with cleaning the registry. Personally, it only helped me after installing graphic mods.
