I agree Bree so far but there could be some corruption, not sure what, but I think we've all seen when the media is refreshed it works. Now the fact it works legacy may shoot that theory down in flames.
The OP says he loaded defaults and that should for a modern board default to UEFI. I downloaded manual and the defaults are UEFI. So that leaves a bad Motherboard. ???
Now one thing we haven't explored, is there a new BIOS available that may correct this situation.
@dejwiu what is your current BIOS level and what level is available on the vendor site. Not saying to update it but can you see what you are running and what is available?
