go to the control panel and go to system (google this if you don't know where this is)
once you're there go to
--->device manager
--->click the + next to Universal Serial Bus Controllers
--->look for the main controllers. usually labeled standard pci to usb host controller. right click that and hit uninstall. do this for any of the controllers but nothing else.
--->reboot without anything plugged into your usb ports and when windows starts again allow it to automatically reinstall the drivers you just uninstalled
--->test out the port
