Want to run dual monitors, but neither work with both cards installed

[crazeinc]

I have a Geforce2 AGP 64mb card that came with this Vaio PCV-RX670 and I wanted to run a dual monitor setup, so I popped in my old Creative Labs TNT and when I booted up the computer, neither of the cards would work, but it sounds like it's booting like normal with no error beers. So I tried a few other pci video cards I had laying around (Matrox, S3 nothing special) and they all did the same thing. I wonder about if the power supply can't handle two, so I unplugged my burner and cd drives and it still wouldn't work. What am I missing?

Have you tried putting the PCI video card in a different slot? Sometimes that makes a difference.

Are you using an Nforce-1 motherboard? Nforce motherboards don't support a PCI card and an AGP card simultaneously.
