Hi, I am Dave, I will help you with this.
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 up correctly
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 5 to enter Safe Mode
If none of the other options are working for you and you can get into Safe Mode, please let me know, we need to stop that AMD driver loading on startup.
