Cannot shutdown or reboot properly

[MrGehab]

PC SPECS:
OS: Win 10
GPU: GIGABYTE GTX 980
CPU: i7 5930k
RAM: 16GB DDR4
MB: Asus x99 Deluxe

So this has been happening to me for about 2 weeks now and I still cannot find a solution to this problem.

Basically what happends is that most of the time (sometimes it works perfectly fine) when I try to shutdown Windows 10, it just gets stuck on the "Restarting.." screen. If I let it be it just goes on forever. Yesterday I tried ALT + TAB and I noticed that "Blocked Shutdown" was active.

If I try just shutting it down normally, it can get stuck on a black screen and my PC remains on. The only way I know currently to shutdown my PC without this happening is to go to "run" and type in "shutdown /s /t 5".

Does anyone know what causes this and how to fix it? It's really bothersome and I'm worried for my PC. Thanks.

I don't know if it will help but you could run start up repair: https://www.youtube.com/watch?v=gFR75FPEdhI&feature=iv&src_vid=z-HKlr_3o0Q&annotation_id=annotation_1799045783

Microsoft generally suggest running a clean boot to see if that works: https://windowsinstructed.com/clean-boot-windows-windows/

Could also try turning off fast boot, it can cause problems too: http://www.tenforums.com/tutorials/4189-fast-startup-turn-off-windows-10-a.html
