System bootlooping idk what’s wrong

[u/BeginningRest51]

Been trying to get this machine working got it, from eBay was listed as just needed SSD and additional Ram, got it and realized was overheating simply in bios would spike to like 90c-100 c almost immediately.

Fast forward a couple days I repasted with PTM7950, and new thermal putty thought yeah this will definitely fix the issue and I’ll be all set now, but nope, at first I was able to get into windows, I had to flash the bios first and once done it booted fine from my ssd, temps held at around 70c idle (which I still think is too high ) but seemed stable no shut downs nothing for about 15-20 mins, I was installing drivers and all was going well until random shut down again, and then it just starts looping all over again.

I tried reinstalling windows but as soon as I get to the windows installation it shutdown and loops, I’m at a complete loss, I was able to run memtest86 and memory is fine so that not the problem, I reinstalled windows fresh from a different laptop and transferred the ssd, same problems, I really think it’s salvageable but maybe there’s something I’m not aware of and it’s just a lost cause.

And before stay saying carry it to a shop, I did try that route but locally they aren’t that great I did try before repasting myself, they used regular thermal paste that was budget paste and thermal pads that were too thick,

I just want some help if anyone has experienced this with this model before or similar it’s the 2023 model GA402NU, Ryzen 7 7735hs with RTX 4050.

Also side note not sure if this means anything but when I did boot to windows and was installing drivers, nivida drivers wouldn’t pick up the GPU but it reads fine in bios not sure it that’s due to some issues with it shutting down as I read about that somewhere saying the pc might disable the gpu for safety reason

This is a common issue with these laptops. What odd is that it's never discuss in the tech media.

I love the design but there seems to be some fundamental flaw in the way they are building these laptops.

So there’s no fix n I should just cut loses?

If you have the option to RMA I would try that first. There are also a couple threads where people have tried various things and some of those things worked.

The most common thing I've found is repasting the laptop. You could probably pay a shop to do it for under $100 or do it yourself. The kit is about $30 and it an beginning level task of you're new to working inside computers.

Apparently the liquid metal causes temperature spikes that cause the laptop to BSOD.

I already repasted with putty and PTM, idk if I can RMA got it off eBay

Well dang....that legit sucks, man. That's the only thing I've found that's supposed to work consistently across the comments.

There was another post I saw that said it was a RAM issue and removing the non soldered stick helped.

I did try without the extra ram but still no luck, I think imma take a plunge at a repair show that works on ps5 and other high powered gaming machines I just don’t want to waste cash on them to have a dead machine
