I just upgraded my Mac Pro early 2008 with the Geforce GTX 680 Mac edition. Works great on the mac side but when I tried booting up to my windows bootcamp drive it would lock up on start up after entering the password in Windows 7. I then loaded the windows drive through parallels and ran all the windows updates. After another restart it would load windows all the way to the desktop but then start updating all kinds of USB drivers and would lock up and blue screen of death. Now when I try and start up windows it goes straight to the blue screen of death. Has anyone had trouble or have a work around or a set of procedures for loading in the graphics card so that my windows drive will still work. I am using Windows 7 and OS X 10.9.2 Any help would be much appreciated.
