What should I do if my computer or software stops responding?
❑ If your computer stops responding while a software application is running, press the Alt+F4 keys to close the application
window.
❑ If the Alt+F4 keys do not work, click Start, the arrow next to the Lock button, and Shut Down to turn off your computer.
❑ If your computer does not turn off, press the Ctrl+Alt+Delete keys and click the arrow next to the Shut down button and
Shut Down.
If the Windows Security window appears, click Shut Down.
❑ If your computer still does not turn off, press and hold the power button until the computer turns off.
!
Turning off your computer with the Ctrl+Alt+Delete keys or the power button may cause loss of unsaved data.
❑ Unplug the power cord. Wait three to five minutes. Plug the power cord again and press the power button to turn on your
computer.
❑ Try reinstalling the software.
❑ Contact the software publisher or designated provider for technical support.
