Hi Norma
I am Dave, an Independent Advisor, I will help you with this . . .

Have you tried all options in the Recovery Environment, all options in there are non destructive to your data . . .
Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down
Do this twice
On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt . . . etc.
Please try each option one at a time, then see of Windows will boot . . .
If the option exists to uninstall the latest Windows 10 update, that would be the best option . . .
Go to Troubleshoot - Advanced Option - System Restore
Check to see if you have a restore point you can go back to
If you do not have a Restore Point, go to Troubleshoot - Advanced Option - Startup Settings and click Restart
Upon restart, press 4 to enter Safe Mode
Once in Safe Mode, backup your data if you do not already have a backup
Open Device Manager and check to make sure all your Drivers are up to date
Reboot to see if Windows will start Normally
If the above fails, go to Troubleshoot - Advanced Options - Reset this PC
Choose to keep your files and apps
Then start the Reset
2
If the above does not get Windows 10 up and running, then you will need to create a bootable Windows 10 USB on another working PC, then boot your PC up from that and rather than choosing to re-install Windows 10, choose 'Repair this Computer' and run the Recovery Environment form there . . .

to download the Media Creation Tool (Click on Download Tool Now), with that you can download the latest Windows 10 ISO (Select Create Installation Media for Another PC), you can create a bootable USB flash drive (min 8GB) using that tool
Then, Boot your PC from the Installation Media you just created (change Boot Order in your BIOS) to begin installing Windows 10
