BEFORE you did a clean install of Windows 10 Pro 64-bit in your newly-built computer, you should've identified the primary devices(chipset, graphics, audio, ethernet, wireless, etc.) in it and obtained the drivers for them.
AFTER the install was complete, you should've installed those drivers.
Note: The chipset driver should always be installed first.
Is THIS the motherboard you have, or is it a different one?
Which "Version" and "Build" of Windows 10 Pro 64-bit did you install?
