Windows 7: Computer not recognizing Ethernet cable after new motherboard install

Computer not recognizing Ethernet cable after new motherboard install

So I put a new motherboard in my PC, and soon after my internet stopped working. When I look in the back of my PC, where you plug the ethernet cable in, it is not lit up as it usually is when you plug it in. I know the ethernet cable is good. My modem has all green lights, im posting using the same connection from that modem on my laptop. I think it has something to do with settings because of the new mobo installed. I am not sure though. Tried googling for some solutions with no luck.

Again I tried the ethernet cord in my laptop, and it works great. I get a wireless connection of my modem great also. So it is not the modem/cable. For some reason it is not recognizing that the ethernet cable is plugged in, and won't get connected. It worked perfect before the new mobo was installed.

Did you load the new mother board drivers?

Do you have the onboard NIC/LAN chip enabled in the BIOS of the new mobo?

Proper drivers installed for that NIC/LAN chip from the manufacturer's site?

Does the NIC/LAN show up in hardware with a yellow exclamation mark as "other", implying no proper driver installed?

As was already suggested... proper chipset and other mobo-specific drivers installed for the mobo, from the generally provider "driver CD"?
