Razer Blade shutting down randomly

[Idkwhat2putheresowhatever]

I know what you're thinking. It's probably a thermal issue. Honestly, everything points towards it being one. But it just keeps shutting down without warning at 57 deg c. 

 

Here's a bit of context:

I bought a Razer Blade 14 2016 for $50 which was supposedly in a rough but working condition. It worked fine for a bit but just shut off for no reason when I was updating to Windows 10 22H2. It would just keep turning off before it reached the desktop. This laptop also has no battery as it's bloated so it was disposed of by the previous owner. For some reason, Razer Synapse thinks it's a Blade Stealth so it cannot control the fans. The fans just refuse to spin up over a certain speed but the temps seem alright. It does spin up to max during POST which is a little odd. I left it overnight and it somehow worked for around 10 mins before it died again.

 

Other things I tried:

Repasting and cleaning the fans 

Using memtest86 (it just shuts off and windows memory diagnostic shows no errors)

Booting into USBs (none of them worked: linux, windows, windows pe. strangely enough, the razer recovery environment works without any problems)

Disabled the GTX 970m in Windows(no difference)

Enabled power saving mode and set the Max processor state to 50% (this worked strangely but it shut off less than a minute after switching back to balanced)

 

So it could be that:

The board is toast

The CPU is toast

The memory is toast

The charger is toast

 

To rule out the charger I'm going to borrow a friend's MSI charger on Thursday. I'm not sure if it would work as it seems to have the same dimensions (5.5mm outer, 2.5mm inner). Would trying to limit the CPU while taxing the GPU rule out the power issue? 

 

It's just a weird laptop overall. I tried using notebookfancontrol with the razer xml file but it doesn't change the fan speed at all.

 

Thoughts/ideas??
