Have you tried reinstalling the latest version of BIOS via USB flashback. Copy the BIOS file to a USB disk, rename it as per your motherboard model or BIOS renamer from your model's download page power down the whole system and perform a USB bios flashback and see how you go. I had exactly same issue with MVG. Got a '00' Led code for no reason, did the flashback thing and everything worked like a charm. Try it!!
