once again if all fails get a 16gb usb stick and download from
https://simplemining.net/this is the download link
https://simplemining.net/page/downloadsome mobos are fuck you
you could have 3 of the exact same mobos
with the exact same parts in every way
and all programmed exactly the same
and 1 of them will only do 5 of 6 or 4 of 6 cards.
I can help you try to do simple mining if everything you do fails.
I have about 22 rigs with 16 on simple mining and 6 on windows 10
BTW you are using windows 10 correct?
