301 Keyboard did not respond to software reset correctly, or a stuck key failure was detected.
8603: System bus error or mouse error.

As the error message says you have a keyboard problem. (Remember there is keyboard circuitry inside the PC as well.)

You need to run through the diagnostics for the PC. As you don't say what it is however it it difficult to advise tfurther.
