Windows Vista on our Macs

I spent Easter in the lab putting Windows Vista and Microsoft Office 2007 on one of the Macs using Apple Boot Camp. Plan is to do all of them. Everything worked except that every time I shut Vista down it goes to a blue screen and a memory dump. Then when I log in, it tells me it crashed last time and would I like Vista to look for a solution. I say yes, and the message goes away. Period.
