Hello @Elijah59 

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

(1) Double check with external monitor connected via vga/hdmi cable.

Do you see (boot screen and) Windows loading on external monitor ?

- Power off external monitor

- Connect vga/hdmi cable

- Power on external monitor

- Power on notebook

(2) Please report back

Hello @Elijah59 

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 checked or replaced

- Short circuit test

- General cleaning ...
