There is an issue with windows 10 where the computer will remain on but the screen will stay black during shut down, you have to wait a few seconds for it to actually shut down. However if this was the case then your PSU fan would stay on. What PSU do you have? It could be the motherboard, but it's more likely the PSU.I've just changed the settings. Screen saver goes to black screen with "Mystify" and monitor off and sleep are set for "Never".
I still have the side cover off so I can see what's going on in there and when I went through the normal shut down last night everything shut down normally EXCEPT the fans and the blue LEDs in them. Even the power supply fan shut off. This morning I hit the start button and nothing happened. The blue LEDs were still on and the fans were still turning. I had to hold the power button and do a forced shut down, then hit it again to get it to start.
