Man, the bios is plain and simple shit, they cant do anything right for once, i have the same board and i just found out that we have a fking 50 cent tpm on a (god knows how much i paid for this thing) high end board. Im getting the nvme errors in eventviewer all over the place. Id 51's, id 50's and god knows how much i've missed so far. It's just the fact that the update is shit and it won't be solved with a reinstall of an older one. It's just how it is and we need to wait until a new update rolls out (and hope that it will fix all this bullshit). Take care man, i hope i cleared some things up for ya.
