You probably picked up a virus that corrupted the bios. You should contact the manufacturer to provide you with Bootable bios cd (taking that is possible to boot from cd now) and support in general. I understand that that model don't come with floppy drive. If it were, then the problem would be solveable without replacing bios chip.
