Windows 10: PC Turn On and Shut Down Issues

Having some serious issues with power driver, actually I'm not sure what the issue is here.1. PC Auto Turns On Once I turn on the power switch, the PC turns on without pressing my power button. 2. Difficulty shutting down, various scenarios for this: A Monitors are off, keyboard may or may not be lit up. PC is running with RGB lights for about 10min+. I will force shut down at this point by holding the power button for 5-10s. B “Shutting down” circle of doom for about 5-10 mins, before blue screen “Power State Drive Failure”. C Monitors are off, keyboard may or may not be lit up. PC

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 shut down, wont turn back on

The fan twitch is it powering up and then the psu is noteing a short and cutting out hence why it wont do it again straight after until it's reset, something is blown or shorted out so you need to do as someone suggested and split the pc out then, on a table build the minimum up as he said and step by step see what's happening.
