I installed a Nvidia Ge Force4 mx420 64 mb 4x2x agp video card but my
computer doesnt recognice it, I tried the add hardware wizard but the device
is not there either, i have no disk to help with installation, do i need a
driver? where do i get it from?anything to do with BIOS set up? my system is
windows xp, pentium lll,ASUS motherboard CUV4X-VM, please help

Roberto, you probably have to disable the onboard graphics chip in the
Bios.
