Hi,
I'm pretty new to the Mac transition and may sound ridiculous to most of you.
So far, I was getting pretty good hang on Mac OS X SL but had to install windows XP, due to work.
Installation went pretty well and for the first couple of days had no issues.
but now as I boot up winXP, after getting the desktop screen, the whole screen goes
black ; tried different things, but nothing seems working. Have to kill the system cold, and could hear the windows shutdown theme.
I wud appreciate any help, and please explain any solution in layman terms..

Thank you in advance for your help.
Cirrus.
