Resetting the Computer
You may have to reset (reboot) your computer on some occasions when an error
occurs and the program you are using hangs up.
If the computer operation seems to hang up, first wait. It is possible that the
computer is processing data. Periodically check the hard disk drive in-use
indicator, if it flashes irregularly, the program may be accessing data and
preventing you from using the keyboard. If you are sure the operation has
stopped and you cannot use the “restart” function of the operating system, reset
the computer.
Reset the computer by any one of these methods:

Press Ctrl+Alt+Del.

If the above action does not work, turn off the computer. Wait for at least
five seconds and turn it on again.
CAUTION: Resetting will cause any unsaved data to be lost.
