Operating System: Microsoft Windows 10 (64-bit)

Hi all, 

So I'm having some problems with an onboard LAN card on a ProDesk 400 G4 Desktop Mini PC. Tried it in a few different network switches and router but no lights appear on the back (yellow/green) and windows reports as network cable unplugged. I've tried a few different network cables and tried those cables in other PC's to verify that they are working. It did work briefly in a 100mb powerline adapter but if slighlty moved it disconnects. It doesn't work at all in any other router or switch. It's also out of warranty (I was given it recently).

Any help would be much appreciated. 

Thanks 

Richard

So slight update. When I use a 100mb powerline adaptor it seems to work OK. I tried a gigabit network switch and no lights so the network card does seem to work in a fashion but only in a powerline adapter? I'm going to try installing Linux and see if its the Windows install and speed authentication issues are the problem.
