Windows 10: Windows Start Menu and Background blanking out after idling

This is difficult to verbally explain, but here is some background context:

• I leave my computer idling over night in order to charge my phone, and I leave it idling when I go to class so I can virtually access it on my laptop
• Whenever I go to bed (~12:00am) and get back from class (~3:00pm) [no using my computer in between], it looks like this when I turn my monitor back on [NOTE: the error message is just from me unplugging my phone and iTunes complaining - I can assure that it is totally irrelevant from my problem]:
  
  And just for comparison, this is how it looks normally:
• 
  
  Any ideas as to what might be causing this? I am able to blindly click anywhere on the start menu and things still open, but I would prefer to fix this. Everything resets to normal once I restart.

• My background goes through a 20 degree hue change every 10 seconds based off of 18 degree intervals (total of 360 degrees, it's quite pretty to watch) so that explains the color differences in the start menus

Satrt menu and Cortan anot working in Windows 10

OT- Cortana setup, Start Menu

When attempting to sign in to set up Cortana, I get kicked out after logging in. The Start menu does the same after a few seconds of idle time. Please help

 

Personal settings not responding and black screen

Hello,

I had the same problem yesterday on my Asus laptop after the window update. After restart, it stucks on a blank screen with a small window on the upper left side of the screen saying "personalized setting". But after idling for 15 to 20 minutes, the desktop
icons and menu come back on the screen and things back to normal.
