Since you have on onboard VGA, go into the BIOS and make check if you have a setting which determines if you are to use onboard VGA or external video card.
Also, I would try to put the Rage card into another slot.
If nothing above works,
Remove the Network adapter and just plug the rage card in. If that works, put the network adapter back (it's ok to use another slot) and see if they all work together now.
