Ever since I installed Windows 10 my PC is constantly booting up on its own. 
I’ve checked & changed every BIOs & Windows settings I can think of but nothing seems to be making a difference.
I am clearly missing something and it’s driving me insane as I feel I have literally checked everything.
Any help would be massively appreciated
