I've been dealing with random reboots on my PC for about a year now, no matter which OS or software I'm using. Initially, it would reboot itself every month or two, but lately, it's happening every few hours. There are no clear error logs on Windows, but when I checked Linux, I found mce errors for CPU 1 and 13, which I believe points to a problem with my 5900X. Could this mean I'm headed for a scenario where I only have 11 working cores? Is there a way to disable the failing core?

To dig deeper into the potential CPU issues, we really need some dump files from the crashes. Check C:WindowsMinidump for any dump files, zip them, and upload them to a file sharing service. Multiple dump files can help us figure things out better. If you’ve only got one or none, you might want to follow this guide to change your dump type to Small Memory Dump.
You might want to run a couple of full loops of y-cruncher stress tests to see if you can trigger any reboots or errors. It's a good way to push your CPU and get some data.
If the component stress test passed without issues, maybe try taking core 1 offline on Linux for a while and see if that helps. I couldn't find a way in BIOS to disable it either on my Asus X570-E.
Got it, is the component stress tester option good enough? I'm a bit worried since most reboots happened while the PC was idle, and just started reboots during use.
