First, click the start button to open the start menu, or press the Windows key on your keyboard. Then click the power icon. Finally, click "Restart." This method is likely the best option if your applications freeze or your computer's processing speeds take a sudden dip. The pop-up window will override whatever is running on your screen. Press control, alt, and delete at the same time on your keyboard. Then click the power icon. Finally, click "Restart." If the control, alt, delete method doesn't work, you can also shut down the computer by pressing and holding the power button until you hear the computer's fan shut off and your screen goes completely black. Wait a few seconds, and then press the power button to turn on the computer.
