hi i have a ga-k8n51pvmt gigabyte board which i have bought secondhand, i have tried with xp and windows 7 but cant get none of the 4 usb ports to work, i have tried the settings in the bios, cmos clearing, uninstalling in device manager everything. they still wont work and sometimes say usb device is not recognized and malfuntioned,
any ideas or is it a common fault and need a new board?
