My MBP has been freezing at start up lately. I never had this problem before. I get the "You need to restart your computer..." message at start up. The computer doesn't even completely boot up. I have BootCamp with Vista installed on it so I don't want to wipe the entire HDD and restore it unless its a last resort. When I boot up on the Vista side, I don't have any issues. Does anyone know what I can do to fix this? Thanks.
