Found this on a trawl of the internet for similar W10 problems. You might have tried this already. (I've deleted the first two steos which just explained howto open Control Panel!). These are not my instructions, apologies if this doesn't address your problem.
3) In Control Panel click on "System and Security"
4) Click on "Power Options"
5) Click on "Choose what the power buttons do" in left panel
6) Click on "Change settings that are currently unavailable".
7) Under "Shut-down settings" un-check "Sleep" and "Hibernate".
Also un-check "Turn on fast startup".
8) Click "Save Changes" and close the Control Panel.
9) Shut down your computer completely.
10) Power on again until you have Windows.
11) Do a typical Restart from Windows.
Windows should now restart normally.
12) Under most circumstances, Fast Startup can be re-enabled after 3 successful restarts (I did 5 to be sure), and your PC should restart successfully from that time on.
