Hi @WinstonH ,
it is hard to tell you the fault without knowing exactly what has been been done to the unit.
If there has been an attempt to flash or update/modify the BIOS, then it is possible that it's corrupted.
But the type of fault you are experiencing can have many causes: unsuccessful Windows update, corrupted booting instructions, faulty disc, etc.
If you have already had a technician seeing the unit, I would advise you to get in touch with your local Medion technical support team and check what are the possibilities for your case.
Regards,
Gehringer
