I'm running an AMD Athlon xp 1800+, 1.53GHz system with 512 ram. my Motherboard is just a cheap azza. My AGP videocard is Nvidia GeForce 2 mx/mx400 64mb. and the videocard i'm trying to put in is a Geforce 4 MX 4000 PCI 64mb ddr. when i put the pci card in my computer with the agp card i get no display on bootup, when i take out the agp card i still get no display. Is there some setting in windows or bios that i have to change in order to get these to work or is this card just bad or not compatable with my agp card?
