Okay.
Try it.
Re-load the OS on re-boot.
Fail.
Open lid.
Unplug and remove Hard drive case.
It was indeed a Hard drive case.
No Hard drive….
That may account for it.

PC World once asked me to devise a test for national chain repair shops. Back in the day my first suggestion was to take the ram that had to be inserted in pairs (yes, I’m much older than 32-bit PCs) and put the DIMMs into the wrong pair of sockets.
But readers cried that I had asked too much when I suggested making a small break in the parallel HDD cable. They said HDD cables are almost never the problem. I came up with that particular test because I had troubleshot that problem myself and thought it would be easy.
Apparently, 3 of the 4 chains recommended a new motherboard.
OMG, they had an empty shell HD case.
Probably an empty display shell!
