The problem has nothing to do with the hardware. In general, the power went out once and when we turned on the servers, this was the problem and it has not been solved until now.
It could have everything to do with the hardware, the 980 Pro doesn't have power loss protection, which means that if power goes out you can end up in a weird state. I think the best way forward now is to recover from a backup! Assuming you have a backup?
