Hello, after some trouble with Windows 7, I decided to reinstall the hole thing. - I installed Windows 7 RC 64bit on a empty WD harddrive with the selected AHCI drivers. - After installing, I updated Windows 7. No trouble after restarting. - After installing the Bootcamp 3.0 (selected Bootcamp64.exe) my system isn't working fine anymore. I got Bluescreen after 1-2 Minutes Windows running on my monitor with the installed 285 GTX, the installed GT120 in slot two seems to run fine and no blue screen on the other screen. But the system always restarts after that and I am not able to install graphics drivers. So I just wanted to know which drivers are best to install with Windows 7 RC 64 bit and a 285 GTX (it's the EVGA Mac Edition) ? Bootcamp 3.0 drivers doesn't seem to work on my Mac Pro (see signature) THANKS for the help !
