If they are out before the operating system loads then yes it is a motherboard issue. It could also be driver issues or a corrupt registry. The easiest way to eliminate them is to back up your data and do a system recovery, not a restore. Those either have a recovery partition on the hard drive or came with recovery disks. This will put the operating system back to the way it was when originally purchased. Basically it amounts to formatting the hard drive, then reinstalling the operating system and drivers. If that doesn't solve the problem then the issue is on the motherboard. If only a couple of these are not working then more than likely the USB power MOFETs have been compromised. If they are all out then the chances are the southbridge has BGA issues.
