Problem with Broadcom mini PCI 802.11a/b/g+bluetooth

I have a problem with my Broadcom mini PCI 802.11 card in my Compaq
V6000z laptop.

I have a Broadcom mini PCI 802.11 with bluetooth installed in my
laptop.

Yesterday, the card just disappeared! It does not show up in the HP
wireless assistant, and it does not show up under Hardware device
manager.

The bluetooth still works fine though.

I reinstalled drivers but nothing worked. I opened up the laptop, and
reseated the card, but that did not solve the problem.

Can you guys give any suggestions.

P.S. I am out of warranty, so I have to solve this problem in my own...
