There is not enough information in the question. I just encountered this issue. Do you want to do a system restore, or a system board reset? The two are not the same. The system board reset will reset the system board back to the Factory Settings minus any Chipset or Biios upgrades that may have been done. This does not affect the hard drive. The system restore will wipe the drive and reinstall the O/S or it will reset the system back to an earlier date. Either way you are going to lose data on the hard drive.
