Hello @ladonshot 

Sorry to hear that you are having problems ... I would like to help you.
 

In the simplest case the internal display cable behind the screen is no longer seated correctly. It has come loose slightly.

Recommendation and solution

In your case: Service is required !
- The computer should be disassembled and checked.
- [Always recommended] Thermal paste for CPU GPU and bridges should be renewed
- [Always recommended] The function of the fan(s) must be checked

- The internal display cable that goes from motherboard to screen has to be checked or replaced

- The screen has to be checked or replaced

- Short circuit test

- General cleaning ...
