I am going to sneak out on a limb and assume the two RTX2070s was last thing you did before it all went sideways after removing them? Have you tried setting the BIOS to default and checking the setting that enables the new hardware check on every cold restart? It is usually some non-intuitive choice like saying yes to, "My OS is not hardware aware."
Re-setting the bios back to default worked! I did not change the bios but I must assume that installing two cards caused this on re-boot?
I can not thank you enough If you have a moment to explain what happened I would appreciate it as I am now considering running two RX 5700 XT cards in tandem to fold (as soon as the Folding @ Home client is updated to enable this card to run properly), as I am confident these will be the new value folding PPD kings.
Thoughts and pitfalls please?
