As PC users we have to deal with the hardships of owning a sometimes less than stellar rig. For this reason alone our systems tend to die if they are infected with a virus for downloading a bad file, or if space is limited and you simply need to do a memory wipe, these problems will require a system restoration or what I, and others, would call a system reboot. Now before you reboot your system, you have to back up your files because if you do not you will lose everything on that hard drive.
