Perhaps the PS/2 port is no longer functioning correctly(hardware
failure), or the system was "updated" with incorrect drivers for the
motherboard, or the motherboard drivers are incommpatible with a system
file update. If there were no known file changes made the possibility
exists the drivers are somehow damaged. Those are possible reasons for
the behaviour described. Time to investigate the various possible
causes. If the hardware is the cause, there really isn't much fix except
replace the motherboard. So file checking and replacement is all you can
really do without c.
