This doesn't happen very often - black screen problems are rarely fixed.  Most often they are repaired with either System Restore or a reinstall of the operating system.

We got lucky today in several respects.

The customer knew what he was trying to do just before the black screen occurred (trying to install a USB->VGA adapter).

He also knew when it happened (last night).

 

The first clue was an entry in the Startups for flvga_tray64

Not much info, but it was likely a startup program for a (yep, you guessed it!) USB=>VGA adapter

Searching for similar drivers didn't yield much - and trying to download and extract files from the download wasn't possible.
So then I searched the startups for "Last Accessed" timestamps.

I found around 6 of them - and they were either directly related to the adapter, or they were related to a video settings program.

So, I disabled them all.

 

And, viola!  I was into Windows!!!

I found the USB->VGA adapter in Control Panel...Programs and Features

And I found another program related to porting video out that was installed back in March - so I uninstalled it also.

Did some updating, cleanup, and housekeeping with the OS.

Then tried to install the USB->VGA adapter - and it worked like a charm!

 

But I credit the success in this to the owner - who was aware enough to remember what he was doing and when he was doing it.

After that, all I had to do was hunt for clues!  Gosh, I love a happy ending! :0)
