Try loading the game without the monitor, go to the settings, and turn the resolution to the default lowest setting(or windowed mode). Close out of the game, hook the monitor back up, and try loading it then.

What type of video card are you running? If you're not sure, can you go to Start->Run(or Start Search in Vista) and type 'dxdiag' and hit enter. Your video card name should be listed under any of the 'Display' tabs.
