Maybe something else in the pc design is to blame then but it seems that electrical noise is getting onto the 5v supply to the usb port. A cheaper(than replacement psu) test would be to use a powered usb hub and see if that cleans it up or to flip from front to back usb ports, or vice versa. A long shot is that a poorly screened usb cable is acting as an antenna and introducing noise so a cable swap to test that may be worthwhile also.
If you are not already getting pc mains supply via surge protected socket or plugboard, do that also. That is a good basic precaution for any expensive electronics
