Recently I bought my iMac, and I've been using Boot Camp since the first day I got it. After a few weeks, my XP has problems booting up properly. Example, when the windows starts(and gos to the place where there is the desktop and the start menu). It just well TURNS OFF automatically! A blue screen will apear(with texts in it) for a very short moment(less than 1 second), it's quite clear to me this blue screen is trying to tell me an error(or maybe not!) but it's just too fast for me to read even a word in it! I'm actally quite angry because of this... The problem was apparantly fixed automatically, for a week only. Today when I was booting up Windows, the desktop comes out, and whenever I point the pointer in the start menu bar, it's always doing the hour glass thingy, and in like 10 seconds, everywhere you aim with the pointer will show this stupid old fasion hour glass! And BOOM OFF!!! Please help me with this, thanks

No I didn't upgrade my RAM or take it out. Ill try to reinstall it but I don't have the disc with me, will get it soon from APPLE PEOPLE!(haha must target them only can)
