At this point, the best option would be to try a BIOS recovery.
To perform a BIOS recovery on this motherboard, you need only to put the BIOS update files on a USB flash drive. The BIOS recovery file is the *.BIO:
Then, while the system is off, connect the USB flash drive and remove the BIOS jumper from the motherboard.
Finally, boot the system. The recovery should start automatically.
If that does not work, please feel free to contact our support department for a warranty replacement:
