What do I do if my computer stops responding?
It is best to turn off your computer using the Turn Off Computer option on the Microsoft ® Windows ® Start menu, located on
the taskbar. Using other methods, including those listed below, may result in loss of unsaved data.
 Click Start on the Windows ® taskbar, select Turn Off Computer, and then click Turn Off.
 If your computer does not turn off, press the Ctrl+Alt+Delete keys simultaneously. When the Windows Task
Manager dialog box appears, click Turn Off from the Shut Down menu.
 If your computer still does not turn off, press and hold the power button or slide and hold the power switch until the
computer turns off.
 If your computer stops responding while playing a CD or DVD, press the Ctrl+Alt+Delete keys simultaneously. You
can turn off the computer from the Windows Task Manager.
Pressing the Ctrl+Alt+Delete keys simultaneously or turning off the computer with the power button or switch
may cause loss of data.
