And it's no bad power quality on mains as someone suggested (it's excellent here) or 'in the air' (whatever that means) if it happens very quickly after buying.
I would guess that a lot of it comes from bad firmware/mainboards, etc. like the recent issue with ASRock mainboards destroying Ryzen 9000-series GPUs: https://www.techspot.com/news/108120-asrock-confirms-ryzen-9... Anyone who uses Linux and has dealt with bad ACPI bugs, etc. knows that a lot of these mainboards probably have crap firmware.
I should also say that I had a Ryzen 3700X and 5900X many years back and two laptops with a Ryzen CPU and they have been awesome.
