I have two different Cardbus wireless NIC cards. I currently run a 10/100MB/56K Cardbus NIC/Modem in my notebook. When I insert either of the wireless NIC's in the computer, it locks up. If I remove the cards, it works. If I put just one of the wireless NIC's in without the wired combo NIC card, it still locks up. If I insert either wireless NIC with power off and startup Windows 2000 Professional, it locks up with about 3/4 of the blue startup bar up on the screen. If I put either in while it is running and it locks up, I can pull it out and it "unlocks". What is going on?
