Mandrake 9.0 RC1 Worked
Thanks for the reply. Unfortunately, I replaced Redhat with a newly downloaded Mandrake 9.0 RC1 and the installer detected my hardware and installed some drivers for it that allow me to get to KDE and Gnome just fine. I may try installing Redhat again in the future or the nVidia drivers on my Mandrake PC, but untill then everything is working fine.
I'm still somewhat of a Linux newbie and I'll probably play around on Mandrake untill the next Redhat release.
