Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

I have deleted the drive and reinstalled - it shows that is fine but then the error appears again with the f12 lit up and on flight mode even though I selected flight mode off.

I have run diagnostics and updates but same thing - I cant connect to the internet wireless as flight mode in on.

I am so frustrated as I requested by brother to assist who is a systems administrator

As soon as you reinstall the relevant adaptor - it show corrupted
