From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Others have already given some good advice, but rather than let it sit and wait to error, use the program "stress"
It'll work specific components hard which can help locate whether it's a CPU/Heat problem, or Memory, or disk.
And if it still fails on random things, take a long hard look at your PSU and measure voltages if you can. But if everything else checks out, motherboard could be it. Tiny cracks/dry joints, even inside the pcb layers, can lead to occasional problems that come and go with heat or vibration and are impossible to accurately diagnose beyond swapping it out.
This definitely can't hurt and will probably help narrow it down, but it's unlikely that OPs problem is hardware-related given that it doesn't happen on Windows.
I can understand that view, but I've personally experienced things where it absolutely can be this and I respectfully disagree with you. I think what OP describes is more likely to be hardware than the OS.
Firstly - different drive for linux. A dying drive can freeze and take down its host, regardless of OS.
Secondly, linux uses memory very differently to windows, especially in relation to caching the filesystem. Linux might be accessing memory that Windows doesn't get to.
We also don't know what loads OP puts on his computer when running windows and linux. Maybe he has windows to game with, or may he uses linux for LLM/compute work and runs it full tilt. Each may do very different things and tax different aspects of the hardware.
It's simply not safe to assume anything when diagnosing intermittent problems with hardware. The only reliable method is methodical testing and isolation.
Very good points.
