Does the 'USB' branch of the tree show the USB ports?
Is there an 'Unknown Devices' branch of the tree?

Either way, the software "device-drivers" for the USB ports are not installed, or not installed correctly, and so you'll get the symptoms that you've observed -- power without device-recognition.

Access http://support.dell.com and click "Detect My Computer", and download and install the device-drivers for the USB ports.

The USB controller driver for Windows XP is a Native XP driver. If you have a problem with it, boot to the safe mode, go to device manager, remove the controller from list, make sure all USB devices are disconnected (Keyboard and Mouse excepted) reboot and let the controller re-detect.

If that doesn't work, then try a repair install of XP

boot in f8 then select last known good configuration. if this fails do system restore to the time when it was still working fine.

Here is Windows Xp requirements:
PC with 300 megahertz or higher processor clock speed recommended; 233 MHz minimum required (single or dual processor system);* Intel Pentium/Celeron family, or AMD K6/Athlon/Duron family, or compatible processor recommended
128 megabytes (MB) of RAM or higher recommended (64 MB minimum supported; may limit performance and some features)
1.5 gigabytes (GB) of available hard disk space*
Super VGA (800 x 600) or higher-resolution video adapter and monitor
CD-ROM or DVD drive
Keyboard and Microsoft Mouse or compatible pointing device

Okay, so it seems you installed Microsoft Windows XP Home on a what was Media Center Edition installation, and the ethernet is no longer worker.
Please refer to dell.com's support section, enter your model, and download drivers that you need.
To find drivers you need, Go to start --> control panel and then go to (under classic view) system --> the hardware section, open up device manager, and then look for ones with a yellow big question mark, and get those drivers from dell's website. Burn these drivers to a CD on another computer, or use a USB flash drive if that does work.
Good luck.
