Alright, I just installed new drivers for a Quadro 4000 Graphic Card on the Mac side OS X 10.6.8. The thing is that when I booted on the Windows side it freezed, probably because it didn't recognised the new drivers installed on the Mac side. I'd like to know, does it's have a way to update Windows so he update the new drivers added on the Mac side? Not sure if I'm clear here, let me know if you don,t understand something. Thanks!
