I switched to Linux again because on this PC Windows suddenly just doesn't run stable anymore. Even a complete reinstall didn't fix it, I assume it is some driver issue or something like that.

It took me a while to convince myself it wasn't a hardware defect. I had very frequent single tab crashes in any browser I used. And regular bluescreens, sometimes multiple a day. But it runs entirely stable on a parallel Ubuntu installation with the same hardware.

If you're unlucky, you can run into weird issues that are hard to impossible to fix as a regular user.
