I have a compact machine which is probably at least 5 years old. It came with Windows 7 and has been upgraded to Windows 10
We have been away and it has not been turned on for about 5 weeks.
When it is turned on it just comes up with the first Compac screen which offers 4 key presses
ESC -Boot Menu
F10 - Setup
F11 - Recovery
It does not respond to any of the keys. There is a noise which sound like a dead/hunting hard disc a few seconds after this screen then nothing.
It is normaly equipped with a wireless keyboard and I have tried 2 different USB keyboards to no effect.
I have tried inserting both a bootable USB stickand a kubuntu live CD and the result is exactly the same.
Any hints as to what to try next.
Thanks in anticipation for any replies
