Windows 7 Crash on Startup at Loading screen

When loading I get the splash screen which then makes way for the loading screen. I get the art in the background and a loading bar begins to fill. As soon as the cursor turns into a claw holding a pick, it freezes. Clicking again causes it to crash to desktop, stating the application is not responding.

I know wireless headphones have been known to cause problems, but I don't use any.
