Unlike humans, computers may have many lives. All you need to do is to format your hard drive and install the system from scratch. However, this is not a good solution. By formatting your disks, you lose all your installed programs, preferences and system integrity. Is there another solution? If you need a personal medic for your computer to provide required treatment without killing the patient first, you may want to give SmartPC from SmartPCTools a try. It's an all-in-one medicine package for your system.
