Greetings Mark:
A couple of messages back I asked how you disabled the onboard video, but you never answered.
If you're unable to completely disable the onboard video, I would have to side with evga. As I mentioned in other messages, many onboard video designs follow the PCI spec correctly and take shortcuts (to boost performance), unfortunately this creates a problem with them trying to co-exist for additional video cards.
I couldn't find anything about the GeForce, but here's something from someone with a Voodoo3:
===============================snip===================
Voodoo3 Video Card Doesn't Work
The Voodoo3 video card has problems with the Compaq Presario computers with the onboard ATI video cards. This is due to the fact that the onboard ATI card can only be disabled within Windows. The Voodoo3 cards do not like any other graphics cards in the same machine (especially onboard ATI Rage cards).
There are 2 ways that may get you round this problem,
1. If you go into the BIOS (F10 when the machine is starting up), sometimes you can disable the ATI card in there.
2. Try disabling the card through Windows,
Click on Start/Settings/Control Panel/System/Device Manager.
Click on the + sign next to Display Adapters and Double click on the ATI Video Card.
Remove the Check mark in front of Original Configuration (Win 95) or Exist in all Hardware Profiles (Win 98).
Close all applications and restart the computer.
If neither of the above methods work, then there is no way of getting the Voodoo3 card to work.

I also found some bad news about the Celleron 500 Presario here: http://groups.google.com/groups?q=%22Compaq%22+%22GeForce%22+%22disable%22&hl=en&safe=off&rnum=4&ic=1&selm=3a73e976.1602087%40news1.rdc1.ab.home.com

If your Compaq is similar to a Compaq Presario celeron 500, then you
are out of luck and no video card will work. That machine with the
intel 810 chipset cannot disable the on-board video. Compaq's
simplified BIOS does not allow for disabling the on-board video. A
voodoo2 would be the only option.

Mark, after reading that, I hate to say it, but you may have no choice but to dump the motherboard or live with the onboard graphics. You might try Compaq TS again for instructions on how to disable onboard graphics as one last attempt at salvaging it.
Sorry for the bad news.
