Laptop boots up to black screen with cursor, shows signs of activity.

I am trying to figure out what is going on with my mom's laptop. Two days ago she told me she was using her laptop and everything was fine, but then she left to do some things in the kitchen and came back a bit later to the screen off. Upon waking it up by moving the mouse, all she got was a black screen with a white cursor. I have looked at it and upon manually restarting, it shows the Windows 10 logo, and then it goes to the black screen with the cursor. There is no login screen either but I do also hear the welcome music. One thing I noticed though is the cursor does have the blue loading circle next to it like it is actually still doing something, and it flashes and spins now and then, as well as the computer sounding like its working, but I have left this on for almost 40 minutes now and it is still just a black screen. It sometimes goes to the off screen and have to move the mouse to wake it up again. Some people online suggest task manager and opening up other windows but nothing works, I can just move a cursor.

My first thought is it is doing something with updates so I figured I will let it be for a few hours while in the mean time I will post this question to see if anyone else has any ideas. The laptop had Windows 7 before and we upgraded to 10 months ago.

Update:

Turns out it wasn't doing updates as pressing the power button makes it go to sleep and space bar can wake it up, still black screen. So I went into the windows recovery tool and startup repair does nothing and system restore failed (which to me screams messed up, though there was only one point I could even choose). So I restarted and it ran a disk check but when I came back it said nothing was wrong, so now I am in the process of returning to the last build. I am not sure what that even means (I assume update) but it has been stuck on "restarting" for the past 20 minutes, but I will let it run for a few hours just in case.

Update 2:

I ended up using that new reset feature which basically reinstalled Windows while keeping my stuff. So far it is working again but if anyone had an idea as to what the problem could have been, that would be great.

How exactly did you get it to work again because I'm having the exact same problem and I'm sorta freaking out cos
I've got work to do

I made the computer go into automatic repair mode, which normally means mashing the F8 key during boot but because of this new "fast boot" they got going on I had to shut the PC off during the boot process (where you first see the windows logo) 2 times before it finally said going into automatic repair. Once you are in there you hit on advanced tools and one of them should be called Reset. There are two different types of Reset though so be careful. One keeps all your files such as photos, music and docs while it reinstalls Windows (think of it as another upgrade, except you have to reinstall any programs you might have). The other one is a complete reformat of the windows partition and reinstalls Windows. Hopefully you get it working too.
