Faulty ASUS TUF B450M-PRO?

[wreakinghavoc]

Hello guys, I'm building a new system by getting a few parts every month so I can actually afford it. This month I've acquired the following:

 

ASUS TUF B450M-PRO

RYZEN 3600

2 x G Skill F4-3000C15-8GVKB

CORSAIR CX650 

 

To finish the build for now I've used old parts from my old rig:

 

2x 1TB SATA 3.5" HDD 7,2k RPM

1X PNY SATA 120GB SSD

GIGABYTE GTX 660 WindForce 2X

 

Installed the drivers from ASUS website and stressed CPU/GPU to see if everything would work, and it did for two days. Now within 5/10 minutes of booting I get a "Ethernet Cable Unplugged". I would disable and enable the onboard ethernet adapter and it would work for another 5/10 minutes and then die until it showed that it was disconnected from the board. The lan leds on the back of the board keep blinking after the adapter is gone from windows.

 

Here's what I've tried so far:

 

- Checked cabled and lan switch

- Fresh windows install with default windows drivers

- Fresh windows install with latest drivers

- Fresh windows install with not so recent drivers(video/audio/lan)

- BIOS default settings

 

Do you guys have any idea of what might be happening other than a faulty board?  Any suggestions as to what else I may try to fix it?
