Need to re-install network adaptor each boot

I'm working on a notebook for a friend that is having trouble with the wireless network adapter. After each boot the network adapter needs to be un-installed before it will work, Vista immediately re-installs the adapter and I can find the wireless network and connect.

Vista Home Premium
Intel PRO Wireless 3945ABG Adapter

Did you update the drivers? Did you try reseating the wifi mini-pci card?
