Windows 10: Taskbar crashing/restarting when I open the Start menu

So, I am trying to open the Start menu, but it's not responding and after that, it crashes and restarts. Every time I press the Windows button to open the Start menu, the desktop flickers and the taskbar restarts itself. How do I fix this?

:)

 

Taskbar hides and shows itself after opening start menu.

Steps:

1. Using HDMI for a second monitor.
2. Open start menu using the icon.
3. Close start menu using the icon.
4. Click anywhere other than the task bars. (e.g. an open window, the desktop, even the first monitor's desktop)
   
5. Taskbar on second monitor slides down to be hidden.
6. Taskbar then immediately slides up to reappear.

If after closing the start menu (step 3), you click on the taskbar, then click outside the taskbar, this behavior does not occur.

Performing the steps on the main monitor's taskbar does not produce this behavior.

This has been happening for as long as I can remember using this laptop (~3years), with different nVidia drivers and Windows 10 updates.
