@aarondrago89304 we really need more information. You say that "what did turn on was a Chipset" but you are not telling us what you mean by that? A chip set, or a component? If you identified it, that would mean that you have take the cover of your laptop. In that case, take some well focused pictures of what became really hot. Heat on components is pretty indicative of short-circuits. Do you have teh tools to perform a board-level repair? Adding images to an existing question

Yep, unfortunately it's almost certain that the PCH is dead. It should not get anywhere near as hot as you described especially with the metal heatsink on!

Unfortunately unless you have the tools and skills to replace a BGA chipset there's not much hope to fix your laptop without replacing the motherboard.

If you want to definitively make sure that the PCH is bad, check for shorted coils around the motherboard close to 0 ohms, be careful as the CPU/GPU coils will by design read very low resistance (2-6ohms).

I'm almost certain you will find one that shows close to a dead short, and that It will be the output of the power supply for the PCH. Inject low voltage at high current and check what heats up.
