If a chipset in a notebook mainboard were to be defective, would the processor, the fan and the start LED work?

Physically, the components should still work, but in practice it will probably no longer start or it will lubricate fairly quickly.

So because my notebook has a permanent look on the screen, I took the notebook to diagnose errors and was told that the graphics card is 100% broken, so I got a new MXM graphics card with the same connector for the graphics card slot and I ordered thermal pads and thermal paste, which will arrive in a few days. In addition, I was told at the service that the mainboard had also been tested and 90% were problem-free and 10% were not stable, so the service man claimed that the chipset was also defective His explanation for this claim is that the graphics card only breaks with the heater (don't know what he means by heater) and the chipset and the graphics card are so close (i.e. In the mainboard) and are cooled by the same cooling system. Is this claim true, because when you start the LED goes on and the cooler goes on as usual, only I have a permanent black screen
