Have a look through these Fixes To Common Errors to see if you can find a confirmed solution.

I don't know if it will work but what you could try do is change your game to Windowed mode and disable 3d mode, both via in-game preferences. This might help, but no guarantees.

Try lowering the settings as much as you can and run it in windowed mode. If that doesn't help, try it in safe mode. First guess would be that the game overloads the system - are you sure your computer meets the minimum requirements?
