well, a format wont help at all until you fix the DMI problem. Clear the NVRAM first, if that doesn't work try removing any non essential hardare (floppy disk, etc) and see if it gets passed that. If no joy, then flash the bios. After that then you can continue.
If you argue with an idiot he will drag you down to his level and beat you with experience.
