Windows 10: PC shutting down during the windows update and not turning back on

I have tried twice to update windows as prompted by my PC. Both times, the computer shut down during the process on it's own and did not turn back on. It says it will restart many times during the process, but I don't think it's supposed to shut down completely. I don't touch the computer at all during the update. It shuts down itself. After waiting for a long period of time hoping it will turn back on magically on it's own, I turn on my PC and it says it's reversing all of the changes that were made and still says it needs to be updated. Please advise.

Turning on/shutting down issue

Hello,
I cannot turn on my PC at all until I unplug something, like when I try to turn it on it doesn't work, I unplug the Display port then I turn it on and after it turns on I replug it.
I also have problems with shutting down, I sit the pc down from Windows and it shows me the "shutting down" thing and then it suddenly shuts off like it's been unplugged from the wall.
I have my AC, phone, monitor, router and PC.
And I'm using some extensions and adapters because the wall plug is pretty far.
By the way I replaced my Mobo CPU, ram and GPU because the previous build had other problems.

Thanks in advance.

PC shuts down after turning it on

Hello. I have a problem with my pc. I have windows 10 installed, and have formatted and installed windows all over again trying to fix this problem but it didn't do it. When I turn on my pc, the windows logo appears for a few seconds and then the computer shuts off. When I press the power button one more time it turns on and loads windows perfectly. This is a problem for me because I cannot hibernate anymore, since everytime I hibernate and then press the power button for the first time the computer shuts off. I don't know what else to do. What do you suggest? Has this ever happened to anyone? Thanks.
