I recently purchased a Gigabyte B450 AORUS Pro motherboard which came preinstalled with A Ryzen 3600 processor. First step I installed with no issuee, all that was wrong was that the memory wouldnt dual channel due to a ram mismatch. I purchased a Powercolour Amd r5700xt graphics card for it today, as soon as I installed, WINDOWS cannot detect the network adapter. I remove card and put old card back in. Still cannot Find the network adapter. I have reinstalled the lan drivers, but says iat cant install because there is no such adapter om the system. I updated the Bios, and reinstalled windows.... no joy at all. Any ideas? The rest of the onboard stuff such as sound and graphics work Fine.
