Boot into Safe Mode, then expand the Display Adapters section.
Right click and uninstall the graphics card from there.

If not, use this method to access the Recovery Environment and uninstall the latest update from there to see if that resolves the problem.
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.
