XPS 7100 Ethernet

[Necrovarius]

Hey all,

I am at my wit's end here. I got a pre-built pc from a friend. It was a Dell XPS Studio 7100. Everything was original except for the GPU, which was upgraded. 

My friends son wants me to build him a PC. So I took the parts from this Dell and rebuilt it in a newer case. I had to change out the PSU and added an SSD.

 

Here is my problem. I cannot get any Ethernet drivers to work. I installed them directly from the website using the service tag, and they install just fine, but when I go to look at the connection, no network adapter shows up!

There have been multiple posts on other sites like mine, but nothing has helped, so I am pulling out the big guns and asking the best community out there for help!

do you see anything resembling an wired adapter in device manager? Does windows even recognize that you have the ability to connect via ethernet?

There is a wired adapter within Device Manager, but of course it has the exclaimation mark. I have tried installing drivers using that directly, but it fails. When I go into network adapters it is completely blank. 

It is like, it knows something is there but no matter what I install for driver, windows 7 has no idea what to do with it. 

Could it be a windows 7 issue?
