After clearing Edge cache, I lost multiple system settings...

I cleared out the cache on my Edge browser and then restarted my computer. I do this occasionally, about monthly or so, previously without incident.

This time, after restarting the computer, the video settings are off so that part of the screen is cut-off all around the monitor, amounting to about half the Task bar at bottom and about half the Title bar in windows (such as Word, Excel, Edge, etc.) ALSO, my audio settings are lost so that I have no sound; it did not recognize the speakers on my TV, and I hear nothing. I went to the Sound System settings and had it look for new audio devices. It found the TV (which has speakers) but it says, "Windows doesn't have a network profile for this device." but it was ALL working fine before the cache clear and restart. 

I then went and performed a Restore for earlier today (before the problem).  That executed but there is no change.

I'm out of ideas and would appreciate anything you might suggest.
