Windows 10 does some weird things from time to time but only when using dual monitors.  If I turn off the second monitor, none of this stuff ever happens.

 

After the screen(s) goes to sleep:

  • Occasionally the workstation will play the sounds for a device continuing to connect and disconnect.  Trying to log device changes doesn't help, nothing appears in the log.  Neither usb or hardware change logs show any changes.
  • Web browsers open in the second monitor will be minimized.  They must be opened back up, then moved back over to the second monitor.

 

This workstation is Windows 10 Pro x64, Build 15063.  Video card is a GeForce GTX 1060, drivers are updated regularly.

Whenever I had a problem with my Nvidia driver, I would use this display driver uninstaller

  Then you can restart your computer, and let Windows find a driver.

I don't believe the Nvidia drivers are at fault.  A clean install doesn't help.

At this point, I now suspect some kind of voltage issue because the second monitor has to use a HDMI to DVI converter.  It might explain at least part of the problem.  

 

Now if only I could find a way to actually test for that....

and have made sure your cables are not bad?  and connected tight?

 

if so the connections could just be dirty or have some carbon built up in the connectors, in this case you could clean them with some zero residue electronic wash/cleaner or plug/unplug the connector at both ends several time to break down the carbon build up on the connections.   carbon build up will effect resistance of cables and also the voltages passing thru a cable.
