Cannot find any network

HI
I am on a ?Fishing expedition? now.
My neighbor?s son has a HP desktop that he used when away in college.
The pc was connected to the college network with an Ethernet cable.
He graduated and brought the pc home and it wasn?t used for two years.
He is home now and trying to use the pc and can?t connect to any network.
He asked me to look at the pc.
The pc has a wifi pci card installed (user installed) and the Ethernet is built into the motherboard.
O/S is WinXP Not sure if it has sp3
Here at home the old d-link wifi that was used died and was replaced by one made by Linksys. The new wifi router works and is able to connect another desktop pc and 3 laptops to the internet.
First thing I tried to do is let the desktop pc look for a wireless network. Windows could not find any networks. My laptop and another laptop can find and connect to a network in the same location.
I opened the device manager to look at the installed hardware and NO NETWORK SHOWED. No wifi or hard wired network. After looking around for a while I went back to the device manager and under the options screen told it to show hidden hardware. The wifi card and built in network showed up along with other things all under ?network?.
When you close the device manager and then reopen it network does not show. Only when you click on show hidden hardware will networking show.
I was wondering, is it possible that when the pc was connected to the school network that something was disabled to maybe a file downloaded into the pc to disable or remove all other network devices? I do remember seeing other items or things listed in the networking when I was able to see it. As far as I know all I should see is a Realtek built in networking and the pci card made by d-link.
I know my description above is vague but I need some help in getting the networking on the computer working.
Thanks

Sorry I am slow to get back here.
What a mess this pc is turning out to be!
When I finally got the pc to work on I was told the monitor didn?t work. I connected the monitor to my laptop and the monitor is working.
I spend 4 days troubleshooting the ps and found the old dial up 56k modem card was bad. When I removed the card the pc booted up and all is well.
Now to the original problem I posted.
Jackmds replied with a link to troubleshooting the pc.
I followed all the steps and cannot get the networking to work.
This is what I found.
After I removed the dialup mdem I went right to the device manager. When I look at the network portion in the devive manager this is what I see.
Direct Parallel
Wan Miniport (IP)
Wan Miniport (IP) Packet Scheduler
Wan Miniport (L2TP)
Wan Miniport (PPOE)
Wan Miniport (PPTP)
(If I remember right all of the above files had a yellow question mark beside each one)
When I click on show hidden files the Realtec NIC shows up. (this is built into the motherboard)

I Tried to remove all of the files above except the realtec. Nothing happened.
I disabled all the files above was was able to disable them.
When I tried to remove the files it would not let me saying the files could be needed for the pc to boot up.

The owner of the pc added a D-Link wifi card to one of the pci slots a few years ago.
The D-Link card is still installed but does not show up in the device manager.
I removed the D-link card and then tried to uninstall and remove the extra files and that didn?t work.
I downloaded the latest files, drivers and installation software from D-link and ran the software. The software installed but could not find the D-link card.
Even as the pc boots up and is done there is a little icon in the task bar saying D-link card cannot be found.
I moved the D-link card to 2 different PCI slots and it wasn?t detected!

I am at a loss and don?t know what to do now. I am afraid the motherboard might be bad.
Everything else works, audio, video, etc.
I went into the bios and restored it to factory defaults.
Is there anything else I can do?
