pci video card into REALLY old PC

[steve472]

I have my sisters PC (1996 IBM Aptiva, win 98se, 80MB RAM, 8gig HD, 2MB of on-board video ram)

I bought a PCI vid card (eVGA PCI MX400 Geforce-2 64MB) .

I install the card, connect the monitor,and I get the first screen that says IBM and it scans the ram as usual. BUT then, I get a black screen with a blinking prompt. if I unplug the monitor and connect it to the original vga port I get a total black screen with no blinking prompt.

so I took the card out, keep the monitor in the original port so I can go into the bios but I don't know what to change. both of the PCI slots are enabled- One for the video card and one for the modem. (the BIOS is called "IBM Surepath utility")

BTW, the eVGA manual says I need a 2.1 PCI slot. Is this pc too old to have a 2.1?

any help would be greatly appreciated.
thanks

Might be too old, but shouldn't be. Try looking for a value called "onboard video device" or somethig like it in the bios, and "disable" that. (you'll have to save that before you exit the bios). Also, you would want to have the new PCI video card in the PC before you attempt to boot back into windows.You may have to switch your VGA cable back to your new video card after you actually do boot into win since you wil use the old onboard one just to get "into" th bios. After that, just manually load "Standard PCI video Adapter" manually when you see "new hardware detected", then after that you can load your drivers from your CD rom that came with the new video card, or download fresh ones to get your new card to actually identify as what it really is (gforce4 MX). You might also want to change refresh rate to at least 75 Htz so your screen won't flutter.
