Instructions
Press the "Power" button to turn off your PS3 gaming console if it's on. Turn it off if the power indicator is flashing red and green alternately. This usually means the interior is warming up.
Leave your gaming console until it cools down, and then turn it back on.
Check the vents on the gaming console, and make sure there aren't any objects blocking airflow. Blocked vents may cause your gaming console to overheat and shut down.
Move your gaming console to an open space to ensure adequate airflow.
