I've been running Boot Camp uneventfully for almost 3 months now.
On Saturday, my MBP went to sleep with a Finder window open to my XP partition (open to the My Documents directory, but no files were open). There were only a couple of apps running, maybe Mail and TextEdit. When I woke it up, everything locked except for the mouse pointer. The mouse buttons and keyboard we completely non-responsive.
Seeing no alternative, I did a power button shut down.
I restarted OS X without issue.
This morning, each time I try to start Windows, it makes it to the desktop for several seconds, then the computer restarts and goes from the Apple sound/gray screen to a black screen.
One of the times, when XP quit, I saw a flash of a blue screen with an error message. Far to fast to read. On one of the attempts to start XP, I was offered choices as to how to start, but of course, the keyboard doesn't work until XP has fully booted.
Anyone seen this or have any ideas?
