Can't install NIC card. I'm running Win XP and I have a PCI Belkin NIC card that I want to install. I have installed it into different slots but Windows won't recognize it as "New Hardware". It has a yellow explanation mark in the Device Manager but won't let me update driver. I have also tried to other cards with the same results. I have gone into the "Setup" but don't see anything to "tweak". Any ideas?
