Do you have two step authentication on your gmail account? If so then you require an app specific password which is entered instead of the account password.

@Steve K. I use Norton along with MBAM pro & as an on demand scanner I use eset's online scanner & Adwcleaner.

I haven't seen this posted here so thought I'd let you all know that those with MalwareBytes software can now reset their license without going through support. Visit http://my.MalwareBytes.com & sign up with the email address used to purchase the MalwareBytes product, once registered & logged in it'll show all your registered products, their ID & Key plus a deactivate all button. This will be perfect for those who forget to deregister their product before trying to install on a different device.

Do you have any USB devices connected especially wireless dongle for mouse/keyboard or external hard drives? If so disconnect & reboot to see if things progress. If not restart the computer & when the HP logo appears force shutdown, do this three times & see if repair appears, there you can try to repair the startup/boot.

Do you have any USB mouse &/or keyboards (Logitech especially) connected? This has been known to cause boot problems.

Have you had the pc from new or is it pre-owned? Can you press ctrl, alt & delete to log out; can you then log in?

Do you have MalwareBytes 3.0 installed? This is a known issue with this program. Have you tried logging out & logging back in? That usually works.
