5th card stoped working

I have had everything set up for about a month and was running 5 3060 GPU'S then the 5th lane stoped working about a week into it. I have tried different risers, and switched GPU's and still nothing. It will boot and show me the Grub but then a black screen with a tint if light. None of the other cards will work too. Any thoughts? It was running in hiveos.
