GA-P67A-D3-B3 Onboard LAN is not detected/broken

[doctorbutts]

Just got the motherboard a few days ago.

I had problems with connecting to LAN within windows ( I would have to disable and then re-enable the network adapter in order to connect), so I updated the Driver, didn't help.

So I flashed BIOS to the latest version (F4) both within the @bios utility and within BIOS. When I rebooted PC, I would get colored lines at the bottom of the screen when windows loaded (but not when booting/loading windows) AND windows did NOT detect a Network Device. I went back into the BIOS, and tried the "SMART LAN" and tried the cable test, it does not work at all. I also tried enabling Onboard LAN Boot ROM, does not do anything. I also tried disabling onboard h/w lan, rebooting, then enabling it, rebooting, does nothing.

So it seems both windows and BIOS does not detect the network adapter at all.

I also tried disconnecting/reconnecting the network cable, tried another one, and the lights never flash at the back of the LAN port.

So I rolled back, tried EVERY BIOS version, both through @bios and q-flash

Also, in the original BIOS with the computer, I had the ability to change PCIE settings, but every other BIOS i've installed since the original do not have this setting at all.

Is the onboard network adapter destroyed?

Hi and welcome.

I would suggest doing an extended CMOS clear and then loading the Optimised BIOS Default settings.

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery overnight before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.
