Your system crashes at various times: sometimes on startup, sometimes when running a software application, sometime when a certain group of applications is running. You suspect a malfunctioning CPU, but none of the common issues seem to be present. You have not configured overclocking. There is no overheating.

Replace the suspect CPU with a known good CPU of the same make and model
A few of your employees have complained that their computers sometimes shut down spontaneously. You have noticed that these employees all work in a part of the building where the air condition does not adequately cool the room. These employees also use CPU-intensive programs. You suspect that the spontaneous shutdowns are caused by overheating. Which of the following is the SIMPLEST way to monitor the temperature of the computer's CPU?
