Remove the accessories. Check the RAMs.
If there was a problem with the motherboard: Program the BIOS.
It could be a graphic problem.

The keyboard is directly connected to the IC SIO and can be a failure of the keyboard jack or the failure of the IC SIO and its internal program and finally the failure of the PCH.
