Reformatted and no internet connection

Back then, I dont think Dell included any of the driver cds so the only cd I do have would be the XP home edition, monitor software, and a utilities cd for the 56k modem.  I cant install the DSL because theres no reading from the ethernet or USB.  Which I need to get online to download those files you listed.  Is there another way or should I somehow burn the required drivers onto a USB drive/CD and go from there?  Just wanted to see if there was another easier/absolute way.

I am also having the same problem, but with a 3000. My buddy bought it off someone and of course doesn't have the cd's. I was wondering what drivers I need to burn to disc to be able to get on the internet to update everything. Any help would be much appreciatted.

After loading the two drivers stated above. Go into device manager and uninstall the usb drivers. Reboot and let them relaod and see if that works. Dimension 3000 drivers are here.

Alright, I downloaded these following files recommended by pudgyone: 

Desktop System Software or Notebook System Software
Chipset or SMBus driver
Processor Driver (if applicable)
Video
Audio (sound)
Input Drivers (keyboard/mouse)
Modem
Network Card

The computer recognizes the ethernet drive now but once im installing the bellsouth dsl service, for the life of it it won't connect to the internet.  It will work on my labtop but not on the tower.  Suggestions?

I tried installing the network card driver and the third time was the charm.  Thanks everybody for the helpful advice.

New problem showed up and i didn't want to clutter up the forum with a new topic so im adding it in here.  It looks like my USB ports are not working with any devices such as my printer or itunes since the reformat.
