Lost my LAN connection

Hello,

I wondered if there was anyone that can help me a driver NVIDIA nForce Networking controller was deleted by accident on my PC and since then i have lost my LAN connection to my pc. There are 2 other computers linked by cable to the same hub that are working fine so i know the internet connection is ok.

I have downloaded and installed the same Drivers and tried to set up a new network connection but nothing is happening. The new network connection doesn't appear and I still have no internet connection.

I am not very technically minded i am afraid so any help will have to be laid out quite simply for me but any advice would be appreciated.

I have also attached the spec of the machine not sure if this helps

many thanks
