Hi, I am Dave, I will help you with this.
If you have disabled all Startup services, the only hope you may have is to perform a System Restore to undo that change.
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.
Go to Troubleshoot - Advanced Option - System Restore
Check to see if you have a restore point you can go back to
