Disable the one(s) you do not want to use.
Reboot.
Then go to start, settings, control panel and double click 'add new hardware'.
In the first window click next, next window choose NO - do a manual add, next window click next, next window select sound,video, gamecontroller, then click next,
in the next window choose microsoft from the left column and "gameport joystick" in the right, then click next, follow the next few self explicit instructions and then reboot.
It should work then.
This is what I had to do to get my Gamecard port recognized after disabling the sound cards port.
And then it just occured me that the able/disable for your Mother board port might be in the BIOS. Boot your PC, get into your BIOS (often hitting F10 or DEL on the splash screen prior to the Windows startup screen).
