Start 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 . . .
Go to Troubleshoot - Advanced Option - Startup Repair
See if Windows startup can repair itself
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
