Looking for a driver

Hey everyone... I'm looking for a driver for an Intel(R) Celeron(R) CPU E3400 @ 2.60GHz. It's running on a relatively recent installation of Windows 7, and I can't get a wired connection to work. I honestly thought the system would just handle the installation automatically, but clearly, I was dreaming. I've tried hunting for them myself, but I'm hitting a wall. If anyone can help me out... I basically need a full set of drivers, or at least the LAN driver so I can actually get online.

It’s not a processor issue, it's definitely the motherboard...

Alright... so what’s my next move? How am I supposed to figure out which motherboard I'm actually working with?

just copy over whatever shows up under the motherboard section

Maybe it's this... an AMD E-350

this looks like another processor you linked
just grab a screenshot of the specs and upload it somewhere—maybe http://imgur.com/

Alright... I'm stuck at the office right now. I won't be able to get to it until tomorrow.
