From a read of that article, it appears that they are feeding it analog inputs, which would imply that it is producing analog outputs. I don’t know if there is a way to evaluate floating point operations on an analog system. That said, my knowledge is very cursory, and someone will surely correct me.
Boot into your bios and check the sata mode. A number of machines that I work with(acer predators most notoriously) will for no discernable reason switch from achi mode to rst optane, resulting in no drive being accessible to the os. Switching back to ahci resolves it.
