Ah, it sounds like this is more than where to find the drivers for a motherboard. When I made my computer I posted the configuration on this website to get feedback how the components would work together. Then, followed the advice.
Since it was a new installation I did need the BIOS, audio, VGA, LAN etc and downloaded them and installed.
I suspect that would be a good way for your friend to proceed, post the components and see what feedback is received. It could be a different motherboard, or components, might be more appropriate. I'm not an expert at this, just used to finding the drivers and other software for my configuration at the ASUS site.
I would also suggest youtube and other similar sites can be very useful seeing how...
