Fried motherboard?

Specs: Windows Vista, 1.8?/2GB
My sister's HP Pavilion Dv6000 computer recently decided not to connect to the internet. (The computer is two years old.)

One day it was working fine, the next day her wireless light (an LED on the front of her case) refused to 'burn' blue.

The light shows blue when wireless is turned on; orange when it's off. Switching the switch does nothing; the light stays orange. I'm pretty sure this is a hardware failure, not a Windows one, but I still started with the software side to make sure.

Windows showed there were problems with the wireless card; I checked the driver for updates, and when that proved futile I uninstalled the card in Windows. Reboot, and the computer DIDN'T find the card. Nothing showed up in Device manager, even when I tell it to update, etc.

So I take the case apart, hoping the card was loose. No go. Removed it, reinserted it, reboot, still no-show in device manager.

Take it to Best Buy, where my sis bought the computer. Geek Squad agrees with my findings; that is, the network card itself is dead. We ordered a new card, replacing it with the exact model HP card (its a 441090-001 802.11b/g Mini-PCI Express). Plug in the new card, boot up Windows, and... nothing is found.

Not only did Windows not find it automatically, I tried to force it through control panel's "add new hardware" dealy-o. Also a bust.

So, bright idea! Maybe it's not the card, but the switch that's broken. Ignoring the fact that Windows should still recognize the card as being there, I dived right into the case to find the switch is not broken, but looks just fine. Nor are there any loose cables. The orange light remains steadfastly orange, and Windows still cannot recognize the card as being there.

My last guess is the motherboard itself is damaged. Anybody know of any other possibilities, things to check, etc.? Any help is appreciated!

Oddly possible that the card is so exact that it is already installed.

See system hardware. Uninstall the one if there and then power down. Power back up and see if os sees new hardware.

Could be bad slot. Might be other hardware issues taking power or resources.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, Make an autorun.inf folder on all usb drives.
