No Driver for Network Adapter?

I was running my computer on Windows XP and it more or less crashed on me so I decided it was time to upgrade to Windows 7.
I did a custom load and everything and it is loading fine for the most part but I cant seem to get an internet connection. I'm using a LAN and the same ether net cord plugged into the same outlet gives my laptop connection no problem but nothing for the desktop.
I tried everything I can think of but with no internet connection how am I supposed to get the drivers I need?
If anyone may have a solution to my problem I would be in your debt.

It is one of the Aurora series, can't recall exactly what model.
Any idea what driver I will need and where to get it?

I'm having the same issue, let me know how this goes and if the drivers work.

Drivers didn't work for my Win 7 64 bit Ultimate

I found the model, it's an Aurora 3500-R4

Doesn't help much as using that doesn't return anything useful,

alienware Aurora 3500-R4 - Google Search

Wouldn't happen to have a service number tag on the computer somewhere would it? If so you can go here,

Dell - Drivers and Downloads

enter the service tag number and find out what is in it.
