Gigabit lan network vs network adapter

[JonHowell]

Hello,
I just made the mistake of buying my son a gaming PC without involving anyone with the knowledge to help me out...
So, after adding Microsoft Windows 7 and thinking the system would work just fine, the error message we get says "no network adapter detected".
We have an onboard Gigabit LAN network, but not sure if I also need some sort of network adapter to complete the set up.
Help!

check in the BIOS if the network card is enabled.

check in the Device Manager if anything is listed under Other Devices.

Did you install the drivers for Windows 7 if you installed that yourself?
