I got this board and at first I had some trouble getting it running properly but this was my first ever rig. Had the same issue as many other people, after loading windows it got stuck on loading screen. But that's somewhat normal, it is detecting GPUs in the meantime, give it a few seconds up to a minute instead of hitting numlock capslock or trying different method to check if PC has frozen.

I plugged 1 GPU at first and set the bios settings properly (enable 4g, mining mode, gen2 etc etc) then installed video drivers and then restarted with 1 more GPU (wait to recognise it), then restart and plug one more (wait to recognise) and so on until you plug all 6 one by one.

The only issue I'm having is it won't force the video on the integrated graphics as long as there is GPU plugged in the PCI-E slot. I enabled integrated gpu in bios and chose it as primary display output, but still nothing. It either displays through PCI-E main slot, or just doesn't display video anywhere. Bios is updated. Also I got 2nd rig recently - exactly same config and mobo - same issue.

So do you have any suggestions what might be the problem? I really don't want to have my video output on one of the GPUs as it affects performance a little bit. Recently heard it might be causing instability with higher overclock which I encountered, it's not all the time, sometimes it's stable for hours, sometimes unstable after couple of minutes. Maybe it's because of the video being on one of the GPUs?
