Imagine that you'd just bought a new Ryzen 7 9800X3D, the best gaming CPU around right now. You drop it into your AM5 socket motherboard and start enjoying the freshly boosted frame rates. After a while, you then start experiencing all kinds of problems, until eventually your gaming PC no longer fires up: the CPU is dead. That's happened to some owners of ASRock motherboards, but it's also apparently occurring with Asus models, and the company has launched an investigation into it all.
In the case of the whole ASRock thing, the company was arguably a bit dismissive of the whole problem to begin with, before admitting that the BIOS on certain motherboards was allowing too much current to be drawn by the CPU in specific scenarios. A little while afterwards, AMD itself stated that "this issue arises because some ODM (original design manufacturer) BIOSes do not adhere to AMD's recommended values."
