on picture look for switch setting and switch it on one of your card
you dont have any mentioned M2 cards in pcie slots? (4XM2G4 or 4XM2HR)I am not seeing the error anymore. I don't believe anything was changed besides taking apart the system and the GPU.
I did notice that at the same time this error message came up I could not boot into windows. After looking at this further the M.2 slots and the SATA ports no longer recognize any hard drives.
Any suggestions on that? Is the board just bad?

mainboard could be pretty much broken
