Hello Hawkigrad,
In your case, I recommend you doing the following steps:
- Clear the CMOS on the motherboard.
- Update the drivers in your motherboard using the latest ones from our download site.
- Install the latest Firmware update on your RAID card.
If issue persists, I recommend you doing a BIOS roll back to the previous BIOS version. You can check more information about the BIOS recovery process at the following link:
