Hello So I did a clean install of Windows 7 64 bit and I ran into a problem where windows would not load the log in screen. In fact during the installation it would not load when windows wanted to start for the first time. This happened while I was hooked into my Nvidia GeForce 8300 video card. My computer also has a integrated card that I switched back to and when I did everything worked fine. I have downloaded the latest drivers and gotten all the windows updates available but whenever I try to go back to my nvidia video card, on start up the screen will go black before I get to the login screen. Any help on this would be great.
