It looks like for me a bad Flash, perhaps you can get more informations from Johnny (http://www.jb8a8f8.com), and even perhaps the Flash chip so you can get some technical person in your country to replace it.

Try to Reset the Bios of the box first, but I don't have much hope on this. Looks like a Bad Flash Chip or it doesn't get the proper power to it (try a confirmed working PSU with another DM box or VU).
