No video after driver installed
I have a System is a new Dell Optiplex 780, running RedHat Enterprise Workstation 5.4 with an nVidia Quadro NVS 420 card installed. When installing the base OS the video shows from the card but is slow. Once the driver is installed (downloaded directly from nVidia) and I run startx the video goes away and the card no longer is active. There is just a black screen and the fan no longer spins on the card.
I have replaced the card with a new one from Dell but I still have the same issue. I have tried re-installing the OS and still no video after the nVidia driver is installed.
The version of the driver is 195.36.24
I have installed the nvidia bug report, installer log, and xorg.conf file (zipped). I'm at a loss and I have a system that is bricked when the driver loads.
Any help is appreciated.
