So the fans and computer were getting dusty inside so I opened it up and took it apart to clean everything. (I obviously turned it off and unplugged it before doing this)
I put it all back together, booted it up and it seemed to be operating normally but it can't find the ethernet port. On the back there are no lights on (before had the orange), when I go to device manager it is greyed out (Realtek PCIe GbE Family Controller).
Device status I get:
Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer.
I've tried turning it off completely, unplugging everything and holding down the power button
