Windows will not load

[Gwyn6]

Hi, hp all in one windows will not load,, after I sign in the screen turns black,,, I've attempted system restore,,, no restore point found.

I'm no hot shot on It, but I've followed posts here and had no luck restoring, loading my windows screen. Any help appreciated.

Thank you, Gwyn.

Dear Gwyn,

  It is possible you turned the unit off during a windows update process, in which case the windows system will not boot/function until that process runs it course. I cannot say if/how-much the update process has been damaged by trying to use 'restore'; however there is a good chance it will be alright if you do the following:

 Before you go to bed, turn the computer-on and leave it alone, once you get to the 'blank screen' ...

 Now leave it running and go to bed, if possible with your modem/lan hooked-up and live (so Windows can 'call-home' in the event it has to recover the update install files). In some cases/circumstances this can take four~five hours (the file re-writing/restoration process = automatic, but slow) ... thus you are best off 'supervising', while sleeping.

 When you wake-up (or six hours have past), it should be sitting there pretending nothing happened - was all just a dream.

 If not - still blank -

a): use the HP Companion/Hardware analytics program (can download it here and put it on a usb), to restore your monitor/screen driver;

b): Windows is critically damaged and needs a reinstall. Go to the Microsoft Windows Community Forum - scroll to April 20 and find the following discussion/thread:

Win 10 pro - lock-out, then complete failure - post 48Hr 'roll-back', post 'update failure' ... How to reinstall from USB thumb?

 Everything/link you need to know is covered in the three posts associated with that thread/discussion.

 Cheers,

Rick.
