multiple monitors PCI card with G450DH

[Petr Prokop]

Hi guys, I am experiencing the following problem:
I am using AGP Matrox Milllnium G450 dualhead adapter for two monitors on PIII AmiBios ver 2.2 mother board msi 6119P2 OS WXPP.
I want to add one more (third) monitor but have only PCI slots available no additional AGP, I managed to get two (SIS or ATI mach64) second hand PCI agraphic adapters to try.
The system well recognizes a new PCI card in the slot, installs proper driver for it, but then the installation returns the Error Code 10 (Black exclamation sign in a yellow circle i the Windows driver manager window) and the card is out of use. This happens if AGP is set as a primnary video card.
If PCI is set the primary card in the BIOS start-up WXPP just hangs-up/freezes on the start up and I am done...
Would anyone have any proposition or information lead what is wrong?
THNX.

If you pull the G450 from the machine and the PCI card still does not work then I'd suggest the PCI card may be broken, you may not have the correct drivers for the card, or perhaps the drivers you do have were not designed for Win XP.

Those are both pretty old PCI cards, and may not be multii-adapter capable.
