New Update: Worked in Windows
Installed Windows 2000 Pro on this box.
Installed the latest windows nvidia drivers from nvidia's site.
Ran 3DMark2001 SE successfully (scored 10233).
Ran UT2003 under Win2000 successfully (played for about an hour).
This leads me to believe it's not a hardware problem.
So now I'm back to square one. I just reinstalled RH8.0 again (kernel 2.4.18-14).
I'm going to try again with the 4191 driver. If that doesn't work, I'll try with older drivers.
nd presumably you followed the same procedures as before to install the Nvidia drivers and configure your XF86Config.....
I didn't actually do anything between hardware upgrades. That is, the 4191 driver was working fine with the old proc and ram. I popped in the new proc and ram and just started the machine. Redhat didn't seem to mind, and I just kept playing. It wasn't until after I reinstalled after the hardware upgrade that the problems came about.
