Windows 10: my labtop screen was divided into two parts

My toshiba tecra m7 labtop screen went black then the computer crashed and restarted itself. I have a blue screen with critical errors. I managed to get it started up in safe mode but the screen has split horizontally in two parts even on booting it . I updeted the bios but nothing . I tried external screen . It worked in full in safe mode and crashed in normal mode with blue screen

:)

 

My HP laptop screen is divided into 3 sections, what has happened and how do I fix it?
