Hi
PLEASE POST ANY RESULTS.
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; Re-Connect the AC adapter.

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).
AND/OR
HOW DO I USE DIAGNOSTICS?

hey lil boy blue,

 

I did all your things but not in that order so I did the 4 second thing and the diagnostic tests before writing the original post they all passed and didn’t help. I then spent ages online speaking to an advisor whose fox didn’t help and as you can imagine I lost the connection as I have to turn the PC off to check if it worked. So I read your response again and the thing that stopped it doing it was holding the power button down for 15 seconds. Now it doesn’t do it at all and I just press the button as normal. No idea what magic that is but thank you 🙂
