My all in one desktop does not boot and shows an error message that boot device not found . (AF0)

Does anyone know how I could open this up so that I can check whether there are any loose cables  ?

I've had this a few times with one of our AIOs. Try switching the PC off, remove any attached external drives, switch off at the wall socket (or remove the main power cord at the rear of the PC) so no power can connect; then hold down the AIOs Power Button for 30 seconds - this has the effect of discharging any residual electricity on the cct board. Then reconnect supply lead and switch on as normal.
