OK. Computer from the office is moved and installed. Booting up now.

Still missing some stuff. And having a completely new screen. . .. .. fingers crossed.

it doesn't like the new mouse. And the speakers just buzz . . . . .

Have you tried to switch it off and on again?

Just switched it after connecting stuff. Found the old mouse and that works.

It even finds the internet . . .

progress!

AND I got music.
