If you haven't found it, you probably don't have one. It looks exactly like a telephone jack, but larger.
They (PCI Nics) cost about $15.00 and are easy to install....

You forgot the user password also?
This program will recover most XP passwords:

I've had good luck with Ophcrack:

This looks very straightforward.
Install the software from the CD, then insert the card and follow the prompts. You'll need to know what kind of encryption you have, the key, and the SSID.

You don't have a wireless adapter.
You can either buy one, or get the Netgear device working.
What's the model of the Netgear device?

Make and model of the PC?
RTFM.

First, you can't expect any support for an illegal version of windows.
Second: Get your drivers from the NVIDIA site.

Is the right monitor being detected?
Uninstall the Nvidia driver, reboot and reinstall.

I'm not sure we can blame Dell.
Probably the same people who don't know how to use the first drive.:)

Can you run the Dell Diagnostics?
Have you checked the diagnostic lights?
Any error messages?
Your HD may be dead.

You need to figure out what's causing the Freezing/Rebooting first.
Check for dust/dirt, fans not working, bad PSU.

You will likely need to format it. Be sure to choose NTFS.

Install the drive properly-you haven't said whether it's internal/external, SATA or IDE, so ask if you need help with this.
There is no need for an OS unless you want to boot from this drive.

Try System Restore.

You should try a system repair:

Can you boot to Safe mode?
If so, try a System Restore.

I agree with caperjack.
You might check event viewer for clues.

You'll need to use someone else's computer if you can't use this one. Download the drivers and transfer them to a jump drive or a CD.

You need to fix the driver problem first, especially the ethernet driver.
Go to the PC maker's web site and get the drivers.
If you don't know how, post the computer model and make.

Did you reinstall all the drivers?
Look in device manager for yellow marks.

Look under Communications.

That really sucks.
You have a 10/100 Fast Ethernet Adapter
Download Belarc to identify it:

Then we should be able to find a driver.

Reboot, and see if the correct card is detected and reinstalled....

Well done. Soon you'll be answering questions instead of asking them.

You need to boot with an XP System CD and do a system repair:
See XP Repair install
http://www.michaelstevenstech.com/XPrepairinstall.htm

That's not what I would do.
When you get to the install screen, you should delete any and all partitions, then create a new NTFS partition using all the space available, which should be 500 GB.
If...

What Caperjack said.
Delete any existing partitions and reformat NTFS.
It's curious that a new drive would show a131 GB unpartitioned space, though.

I don't know, but:
I looked at my icons and saw the same bar, which I had never seen before. This printer had been deleted some time before, but had never disappeared. I noticed it had docs pending,...

What's the purpose of the new disk?
Any chance of getting the disks you should have received with these machines?
Why not just make a disk image?

Remove the entry from the startup folder.
You are in serious need of more memory.
Most people think 512 MB is the minimum for XP, and RAM is cheap nowadays.
