Ethernet not working on new build

About a month ago I built my first computer. It's all working fine, and I've been using wifi since I've been out of range of ethernet.

The other day I moved my computer to where it will be in range of ethernet. Unfortunately, I can't get it to work. I've installed and reinstalled drivers. The ethernet plug is on my MB (MSI P67A-GD53 (B3)) It's enabled in BIOS and in windows (windows 7, 64bit). The same ethernet cable works when I plug it into my laptop.

Here's ipconfig /all:

Your ipconfig is blank.

Try this: Connect the cable. Go into Device Manager and disable the wifi adapter and uninstall the ethernet adapter but leave the ethernet drivers there. Reboot. Windows should do the rest.

Thanks for you suggestion, but it didn't work. I disabled the network adapter, then uninstalled the ethernet adapter (the only other adapter listed besides wireless was 'Realtek PCIe GBE Family Controller', which I assume was the right one). When I rebooted it windows automatically reinstalled the ethernet adapter, then proceeded to not work.

Not sure if this means anything, but when I enabled the wireless adapter in the device manager, another network adapter popped up for just a second: "Microsoft *something* #2".

Also, the ipconfig is there, it's just in a spoiler. It should have reduced it to a scrollbox, but not sure why it didn't. Just click the spoiler button to show.

I also noticed that when I go to Control Panel -> Network and Internet -> Network Connections then it shows:

Local Area Connection
Network cable unplugged
...

Could it just be a broken adapter? The ethernet cable doesn't click when I insert it.

Yeah, it definitely could be. I mean, that's the plain meaning of the errors, isn't it? Look inside it and see if the pins are messed up. If they look OK, do that boot thing again, only this time uninstall the drivers too, and let Windows find the ones it wants after reboot. Worth a shot.
