Tom,

I have had the same problem on two NT 4.0 Workstations
running SP4. Once you try and change the video card, it
keeps defaulting back to the 16 color VGA driver. I spent
1.5 hrs on the phone with Microsoft Tech support to no
avail. They gave me an open case #, and are going to
investigate. On one of the systems, I was going from the
onboard video to an ATI Rage II+, and had the exact same
symptoms you described. Finally resorted to formating the
drive and re-installing (drastic, but it cured the problem
<g>). The second system had a Trident AGP card, and I was
putting in a Diamond Stealth 2000 Pro (PCI). Once again I
had the same problem. I called MS and jumped through the
hoops for them ;-), and they finally came up with a
sugestion, that I have not tried yet. They suggested doing a
paralel installation (preferably on a different partition,
but not necessary), installing SP4, setting up the video
card (it should work), and then copying over the system
hive. However, there is a "minor" <g> problem... if you do
this, you will end up reinstalling all your apps, and there
are probably other "minor" side effects <g>

Anyway, I still have not been able to fix the second
machine, and I don't want to do a reinstall so I guess I'm
kind of stuck for the moment.
If I hear anything, I will post it.
