Ethernet Port Suddenly Stopped Working

HP Recommended
HP Compaq DC7800
Microsoft Windows 7 (32-bit)

I need help please... anyone with any information pertaining to this huge issue I have been having with my computer.


I have to directly connect to my router with an ethernet cord because my computer isn't wifi capable. It was directly connected via ethernet cord and was working perfect. Suddenly out of no where, the icon on the bottom said it wasn't connected (when it actually still was) and although it is connected it won't recognize it anymore. I have tried getting a new router, a new ethernet cord, and restarting the computer as well. 


if anyone has any help with this I would be so very grateful...


Thank you.
