@GaryT3 -- your issue could be "hardware" -- your disk-drive is beginning to fail, and components of Windows cannot be read from the disk-drive, or "software" -- corrupted files on the disk-drive.

While Windows is starting-up, with the "spinner", hold-down the on/off button for 30 seconds, or until the computer turns off. Turn on the computer, and repeat when you see the "spinner". For a third time, turn on the computer, and repeat. Finally, turn on the computer, and Windows 10 should boot to its "Recovery Console". It should run a "Check Disk", to test the logical integrity of the file-system, and to try to "repair" the Windows start-up procedure.

Beyond this, it's time to hire a professional computer technician.

Thanks for the assistance.  I tried your recommendations, but it didn't work.  The repair process did not work and I could not even use a system restore point.  I decided to re-install Windows 10 and now it seems to be working.  I set up a different user ID.  The problems is that all the files (which I had backed-up) and not there.  Could they be associated with the user ID and I was having problems with?

A "clean" install will have deleted everything, including your personal files.  

Had you been able to logon, there is an option to reinstall Windows while _keeping_ your personal files.

Last chance: open the "C:\Users" folder, and look for the names of the folders inside this folder. There is a small chance that one of the folders has the name of your previous ID.
