[2.1.19] Crash seemingly spontaneously

[Riccars]

I've had a couple crashes on this build, they seem to happen without any rhyme or reason, this time i was simply walking to the left. Another time I tried to save and went afk and it crashed while I was gone, possibly during the save. Space age with quality and elevated rails no mods. I've included the last autosave, from about 5-7 minutes before the crash

Looks like the ryzen defect, make sure you are on the latest bios, see 114778.

I did recently update my bios but I think I've never done my chipset, I'll give that a try.

[Riccars]

It did crash one more time, chipset and bios should be up to date. Hopefully its not a failing hardware issue.

...

That is a different crash, this is a hardware issue.

[Riccars]

Still working on identifying the cause, RAM appears to be ok but I'm going to do the rest of the testing overnight. Hard drives appear ok, check disk had to repair something.

The only thing happening at the same time in event viewer is an error with the microsoft gamebar, Not sure if that's the cause or the effect of the crash.
"The server Windows.Gaming.GameBar.PresenceServer.Internal.PresenceWriter did not register with DCOM within the required timeout." Trying to see if I can resolve this in case it is the cause. I'm still on Win10.

A month ago I had GPU issues that got resolved with updated bios drivers, that's my newest component so I'm hoping that it's ok.

At the moment Factorio is the most reliable game at producing the crashes, more so after the pc has been running a few hours, but I'm not seeing any crazy discrepancies around crash like temps.

[Riccars]

I still cannot identify the cause, every time I tried to test an individual piece of hardware it comes back ok. Removing gamebar didn't change anything besides not leaving a log in event viewer. Factorio is literally the only program I can get to reproduce my issue and only at random. First half of today was fine, then multiple crashes in the afternoon. Yesterday two crashes killed windows at the same time. Unfortunately, there's no log or dump files from those crashes even from Windows. I'm stuck between believing it's either the CPU, Mobo, or C: drive all three I'm not looking forward to replacing and don't want to do blindly. If y'all have any ideas, I'm all ears.

4th crash today windows had to restart with it. Got an event.

event ID 18
"A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error

Later tonight I had another unique crash, windows survived but factorio crashed in such a way the application ended without writing crash logs.

event ID 1000

I'm leaning on this being the CPU, I'm confident the RAM is ok. If the c: drive is failing I'd expect more widespread issues. I'll throw in todays crashes for whoever wants to look at them, but I probably won't update again until I replace parts. I don't think I had a cpu fail on me before, I think this one is about 7 years old.

[Riccars]

Final update, replaced CPU, it's been about 3 days without crashes.
