When I push the switch button, it starts working, but after 30 seconds it shuts down automatically.

I then dissembled my system and applied new thermo paste on CPU, as well as new thermo pads on GPU, North and South bridge chipset. but nothing has changed!!

I disconnected the yellow cable of CPU fan so it works at the highest speed, but GPU is still HOT, and the laptop shuts down like emergency. I think there is some kind of problem of any little resistor, or capacitor as the GPU appears to be getting to high a voltage and that's why it gets HOT (between 70-85 celsius )

So what can i to do ?

thanks a lot

I thought the screen was the cause but it seems to be a motherboard issue. I first discovered that if I bent the board (lightly) in the corner where the screen cable connects to the motherboard, the screen would illuminate. I thought it might just be a short or something. Then I checked if pressure cause somewhere else in the board was the fix and this seems to be the answer. My guess is a capacitor or something but I'm hoping someone with some more experience can provide a more concrete solution.

Some videos to show my findings
