Clearly, you have a hardware/bios issue. Try the following steps, but be careful if you're not familiar with any of the processes listed.
Shutdown your computer and reconnect all cables between your hard drives and motherboard as well as the power cables to your hard drives. Reboot and see if this makes a difference.
Shutdown your computer and reset your bios using the reset pins on your motherboard. Temporarily removing your motherboard BIOS battery will ensure the reset. Reboot your PC.
