Windows crashes on shutdown/restart

[Agrajag42]

I've installed Windows on my iMac, and everything works fine except that about every 2 out of 3 times I try to shut down or restart the computer from Windows, it blue-screens. Someone reccommended that I go in and disable all the devices in Device Manager that weren't supported by the drivers Boot Camp gives you (like the iSight), but that doesn't seem to have fixed the problem. If anyone else has suggestions on how to fix it, it'd be a huge help.
