Please let me know if this helps.

Thanks. I just bought a usb wifi adapter and used that to get access to the internet and use the dell tool to update the drivers. However, after much frustration with XP I have been wondering about upgrading to win 7. Is it recommended to do so with only 2GB ram though? Thank you

Its recommended to upgrade to Windows 7. This system should take 64 Bit Windows 7 and 2 GB of RAM is minimum requirements for Windows 7 64 Bit.

Windows XP has reached End of Life and is unsecure, likely you will run into problems with its continued use online.

Dell do not list Windows 7 compatible drivers so I made an unofficial set here:

And unlike Dell I list the system drivers in the correct installation order and mark variants.

For Windows 7 the Ethernet driver will be inbuilt.

The wireless card will work natively with Windows 7 however you can get an up to date driver from here:

In order to identify your wireless card follow the steps here and perform a search on the page for the first line of your hardware ID:

If you have issues post your hardware ID and I can tell you the driver directly.
