Faulty drive, inflated battery

Hi

I bought my razer blade 15 base model (2018) about 3 years ago for uni/gaming...

TLDR: (it might be relevant idk)
As covid-19 came after using my laptop for 6 months in another city (where uni was at), i moved back home for money reasons (uni was remote) and didnt really use my laptop that much for about a year and a half (on holidays, hdmi to tv, streams etc). Over the years, my touchpad stopped clicking, or it was really hard to press

I then started using it again about a year ago, when crypto rolled in (for me) and Uni was starting again

One day, at a job my laptop randomly got a BSOD, and there was no way for me to recover my data (didn't have a m.2 adapter), so i just went on and reinstalled win 10.

Came November 2021, upgraded my 2TB HDD to 1TB SSD

And ever since that BSOD, i got a blue screen now and then, but it was ok on the next start so I just assumed it was all good.

Then came 1st of September 2022 (5 days ago)

And I started getting blue screens every ~15 minutes of laptop turned on.
At some point when i was quickly making a backup, laptop got a full bsod

Took it to a repair shop, he told me it was the m.2 SSD (after tests).

Went to the store, got a new m.2 ssd and when I went to replace the m.2 SSD, i also checked the touchpad and noticed my laptop had an inflated battery. After the replacement I got a blue screen 0x0...21a 5 times in an hour, and after that it went back to normal (after another reinstall)...


*I now see this wasn't really a TLDR* .-.

Any idea why my laptop has an inflated battery (it also drains really fast)? Or how come a 3 year old m.2 just goes boom all of the sudden?
