Double check in your BIOS to make sure your network port is enabled. 
Maybe try a load BIOS defaults.

You might have to reinstall CentOS and see if it recognizes the network
card.

Do you know if the network card is even working on that computer? It is
possible that NIC might not be supported in CentOS7, but this is
unlikely, I have not run into that type of issue in years.
