It's most likely your motherboard going then.

I bought a new USB card for a PCI, and now I have fully functional USBs.

IMO, be carefull if you have random USB ports and PS/2 ports dieing then the motherboard is going... Could be blown caps, try checking the motherboard and make sure none are bulged out and the such.
