MSI 6QE PE60 freezes at BIOS

Bought a laptop off ebay for repair. Description said it "didn't want to boot anymore, and if it did boot it freezes" with picture of MSI logo splash screen.
So thought it would be some typical bad ram or overheating.

Received the laptop, had only maybe 2 screws in bottom case....I felt thing were going to get imminently worse.
The CPU heat pipes had a hole in it and IDKWTF they were trying to do, but they "opened" up the brass pipe bends with pliers or IDK what. So I guess they thought the insides evaporated and they punctured it to see?

Anyway, ordered new heatsink. Everything feel normal. I feel warmer air coming out fan vents after its on for a bit. Heat pipe seems to be evenly carrying and scavenging the heat.

But kinda the same issue/symptoms, besides shutting down from overheating.

I try to boot, it gets to MSI splash screen, so I spam the DELETE key to get into BIOS. It literally freezes after 3-5 seconds, and just stays frozen on blue bios with timestamp frozen. No shutting down becuase i'm sure HSF is doing its job and nothing is overheating now.

I shut the laptop down by holding power button, and it never really gets back to the MSI logo splash screen. It takes waiting a few minutes and then it will atleast get back to msi logo and bios, then freeze.

So did they game this laptop too hard and the CPU is messed up or MOBO is messed up? But what component is failing? The laptop has overheating shutdown values, so it should shutdown before irreversible damage?

Any ideas? i've tried taking battery out and MSI gives you a reset button also. And all the other power drain techniques.

Edit: I think MOBO or GPU is bad....I had an old Dell XPS laptop that would only load Ubuntu. Well I got Ubuntu to boot from live cd/usb one time. It stayed running for a good while.
