I have a motherboard that I believe has a short on the PS/2 ports. The
computer sometimes boots normally but most of the time I get an error
saying that there is a keyboard error or no keyboard present. Should I
replace the motherboard or is there a way to fix it?

The usual cause is an SMT capacitor failure which shorts one of the PS/2
signal lines to ground. Intermittent is harder to track down than
permanent failure, but usually probing the signal lines with a scope
while pressing keys will reveal which signal is the problem. Removing
the corresponding capacitor to ground usually clears the fault, but the
cap should be replaced as it protects the super i/o chip from spikes on
the PS/2 signals.
