Thanks for the info glc!
I didn't have anything on the drive that was worth saving so I did a clean install. Why not? Brand new machine I should have a clean version of the O/S.

The machine is purring like kitten. One of the display lights appears not to be working. I will look at that situation next. It is so nice to know exactly what is under the hood.
I will NEVER buy another desktop again!
I still can’t believe that I built this computer myself!
