I'm looking to upgrade an old emachine.I tried replacing the current PCI card(MX2 400 64MB) with a ATI 9600 AGP video card and the system cannot find enough resources to set up the secondary display(DVI) it's a really fussy machine.
You need to uninstall the Nvidia drivers before attempting to install the ATI card... Run the uninstaller with the PCI Card in, Shutdown... Make sure you change the BIOS do display AGP First, NOT PCI... Save BIOS Changes, Shutdown... Swap Cards, install ATI Drivers... Should work..
