Good old windows 10 !!

Had the same problem but got it booted up again by switching off and on at the main power. It also would not boot up if it went into sleep mode. Having got it fired up, I decided to go back to win 7 but at the last moment I had the chance of fault finding and worked through this (but you need to have some form of Microsoft account even if it is with your own email address) Anyway having got my account sorted I went on line to a chat help desk and the engineer worked througha few things and took over control of my computer and eventually said, it should be ok and to test it.

It worked fine and it wakes up having gone into sleep mode and boots up if I have shut it down.

Are you both having the "Dual Screen" issue. It thinks you are running dual screen and leaves your only screen blank as it thinks it is displaying login on the other screen. Symptoms are that it sits there with a black screen and your screen usually turns off due to inactivity.

Lots on the internet about curing this.

After the win 10 up grade, my puta shut down,and now will not switch on!

Could be that your computer is not powerful enough in ram or processor. Did you check your spec a against the minimum for W10 before your installed it?
