Regarding replacing the PS/2 port, you can try and see if it solves your problem. No harm in doing it, as long as you make sure dili ma-damage ang ubang parts sa board.

But in my experience, PS/2 port problems are normally caused by BIOS-related issues. And if after re-programming your BIOS the problem is still there, there's not much you can do about it because the PS/2 port controller is integrated into the chipset in most cases.
