Right, I gotta agree with whocares and technical as well. The thing is, it’s just out of software competence to do such a thing. Even a virus can’t do this (with some exceptions, such as Win32.CIH, which under some circumstances can succeed in rewriting (reflashing) your BIOS. But this only worked on old motherboards – it’s much more secure now…). The chance is like one to a million… 
To sum up, it must be a HW issue (or a disconnected cable).
