Try mo muna remove ang CMOS (unplug mo power connecter from the MOBO before doing this, there should be no power supplied to the MOBO while doing this) for 5 seconds, then lagay mo uli. Kung automatic sa floppy siya mag boot, download ka ng BIOS fix, search mo sa google yung brand ng MOBO mo then kuha ka latest version, then load mo sa floppy disk, then load mo ang floppy disk while the computer is booting.
Try mo lang, pag ayaw talaga, unfortunately, you need to thrash your MOBO.
