Okay, so I installed Windows using boot camp on my Mac Book Pro. It had been working fine for a couple days, but last night I was running Windows and closed my laptop because I was going to bed. This morning I opened it, and tried to wake it up but it just stayed at a black screen. So, I manually shut down the machine and turned it back on and tried to boot into XP. I got to the point where XP is loading and after that the screen goes black, flickers a couple times, and restarts. This happens every time I boot into XP. Anyone know what could be causing this? Thank you.
