Wait, I misread your post, you say it freezes during the loading screen... but do you at least give it a chance to continue normally, or have you just been immediately pressing Ctrl+Alt+Delete?
I have a similar rig to yours, and the same thing happens to me in L4D, as well as UT3 or Borderlands loading screens, that is, a momentary freeze, but it doesn't actually have any impact on gameplay, or the game's stability. Maybe that's the case with you as well?
