Question Computer crashes but with no Blue Screen ?

[Dusky Crow]

Problem: Computer Crashing

Aspects of crash:
1. Immediately goes to black screen, no blue screen of death.
2. Mostly, if not only happens when i'm browsing the net. (Mozilla Firefox)
3. Computer does not turn off all the way, but instead initiates a reboot automatically.
4. Sometimes weird audio plays if sound is coming through my headphones. Like a loud crashing computer sound on repeat until it begins restarting.
5. Crashes are infrequent. Can go some days without a crash, sometimes only once a day, at worst maybe twice.

So far I haven't diagnosed much, as i'm not sure where to begin. There doesn't appear to be any temperature issues and Windows Memory Diagnostics hasn't identified anything. I'm assuming Firefox could be an issue, but i'm not sure why that would be the case or how I would even check that. Speccy is also listing 86-92 degrees on my CPU but my Ryzen Master software is showcasing it at 37-42 while idle. This could also be an area to look at. Any ideas on how to start looking into it?

Edit 1: I've checked my BIOS temperatures, and it appears Ryzen Master is reading it accurately. Not sure why Speccy is saying it's scalding.

Crashes are somewhat random, mostly seems to happen when i'm browsing on firefox so i'd have to test that for multiple days to see if a crash occurs. Any other potential areas to look into?

Update:
After forgetting about it for a couple weeks and switching to Google Chrome and not bothering with Firefox, my computer hasn't crashed at all. I'm thinking Firefox weirdly caused the crashes. I'm not sure why this is the case, but i'll switch back over to Firefox and confirm if it happens again.

Tested Firefox for two hours, lo and behold, Firefox did indeed restart my PC once again. I'm not sure what specifically it is with Firefox that's causing this, but Firefox definitely seems to be the source.
