I've been experiencing a black screen with a frozen cursor (everything is basically frozen) after waking up from sleep in Windows Vista. The Mac side of things are fine, and its super annoying, because I have to do a hard reboot each time this happens. I tried google, but it appears that everyone that has a problem similar to this has a responsive computer or just needed a different driver for their graphics card. I've tried installing a different X1600 driver for this, but it didn't work. I'm on a MBP1,1 running Windows Vista SP2 (fully upgraded) with Bootcamp 3.1. If anyone has any ideas, it would be greatly appreciated.
