I'd go to the Fedora website on another computer and download a Fedora
7 Live CD iso and and burn a CD. The F7 Lived CD has the option to upgrade an older instalation. This will get you the latest kernnel. Then download the latest NVidia Linux drivers http://www.nvidia.com/object/linux_d...100.14.19.html
dated September 18, 2007. Also from the NVidia site"NVIDIA now provides a utility to assist you with configuration of your X config
file." At the site "X config" of that line is a link to that utility. It should keep you from missing any changes that need to be made to the X config file.
