As the title implies:

The onboard Ethernet port goes between not recognizing the Ethernet Cable to "Finding Network" and back again every second.

What I know:
The cable, the wall jack, the switch, and the router all work fine because I can plug it into another computer and to runs as it should.

What I've tried:
changed the Ethernet cable
changed wall ports
changed ports on the switch
reset the switch
reset the modem
power cycled the machine
Reset winsock and IP with netsh
Set the speed of the port via Device Manager and through the BIOS
uninstalled and reinstalled the drivers
tried a different Ethernet card and then followed all of the previous fixes.

I've tried to go into the modem to reset the device's information in case it was keeping some of the information but its a P.O.S from Verizon so no joy.

The mother board is:
MSI ATX DDR3 2600 LGA 1150 Motherboards Z97 MPOWER

The only thing that I can think of is that while I was on it, the internet went out. We had to get someone from Verizon to come and fix the issue. I'm wondering if my motherboard wont be able to connect via hard wire again.

It is currently work while I'm using a wifi adapter.

If someone can help before I lose my mind, that would be great. Thanks.

Reset the bios to defaults, disable the onboard network card, install the add-on network card you have, get the latest drivers from the vendor online support site.

Make sure everything is clicked in properly, test it again. If the issue continues, create a Linix Live boot disk (you can find instructions online), boot the system off that and check the network connection using that. If it works fine, the issue is somewhere in Windows. To test that you can use a spare hard drive, install Windows clean on that (don't worry about activating it yet) and see if that works OK. If it does you need a clean Windows setup.
