Why does Scandisk or Defragmenter continuously restart?
It is due to some interfering application. To use them properly, you have to hit CTRL+ALT+DEL and end everything except Explorer and Systray. We have to take into account that this will end our firewall and antivirus, so do it when we are not connected to the Internet. Also, check the power options and see if the hard disks are set to disconnect or the machine suspends. And also disable the screensaver.
