Win98 SE thinks I have two monitors and is blank screen on me

I removed the old PCI video card from my wifes PC and put in the TNT2 card I recently bought.
On reboot it came up with a blank screen, all black.
I put the PCI card back in and got all rebooted and then switched the monitor from one to the other. Sure enough, the Windows screen was displayed on the PCI card and a 'pop-up' window saying 'Window has successfully set up your secondary monitor' was on the other.
I have been around and around with this thing and can't get it to work right.
I've gone into safe mode and deleted all the adapters over and over, reinstalled several different versions of the nvidia drivers (3.72, 6.31, 6.47, 6.49).
I've gone in and removed all nv*.* files from my Windows directories and tried reinstalling again.
What's the secret here, it seems like I have done this before, but it was a long time ago and I don't remember what fixed it.

Wait, so when you have the TNT and the PCI card in there it says second display set up? I had a similar problem:

I added a PCI card in there, and windows detects it, but nothing would show up. It turns out the PCI card was missing a BIOS, so it can't display anything but it was still detected.

Does the TNT display in DOS? Just in Windows it's blank? What monitor are you using? It could be the refresh rate is too high, and did you set Primary Display in the BIOS to AGP? Hopefully this could help.

Yeah this bios has it like a choice between 'AGP/PCI' or 'PCI/AGP'. I have it at the first one.
No, it isn't the refresh rate, it's the problem where Win98 SE thinks you are trying to set up dual displays so it defaults to having the PCI be the primary display. Only thing is it won't let me change it. I think anyway that's what it is.
Both cards work separately in different systems.
I will try putting it in another system and see if I can get it to boot right and make sure it's set at 640x480 by 16 colors by 60hz before I move it back into this system again.

Finally put in a different AGP card and it loaded. Now it does the same thing if I try to go back to my PCI card or if I try to change to the tnt2 card. THis is really frustrating.
