You probably need to remove these ports from your computer or isolate them.(I have no idea how to do that btw , you need to ask a computer engineer.
Hovewer I found these solutions:

Most of the problems were caused by something called jumpers.I remember having seen this on BIOS something with jumperfree configuration , but I am not sure.
If I was on your situation , I would play around with the motherboard since I don't have a lot of money to spend on engineers , but I suggest that if you are not sure about it don't try to mess around with motherboard because yours is expensive.You should better get your pc checked somewhere when you have time.
