windows 7 was working just fine for me as a bootcamp partition for a long time already (a year i think) and all of a sudden, it crapped out on me, my macbook pro was on the windows 7 pro bootcamp partition, when all of sudden, my macbook seemed to autoshutdown, i just have a black screen, as if its off. I turn it off and then on and select the option button to load windows 7 again and it just shows me the splash screen and stays there for a long time. any ideas how i can fix this issue?
