How to Get a CPU's Temperature

When it comes to computers, heat is not your friend. While all computers generate heat from their day-to-day operations, each machine has a limit. An overheated CPU can damage components, reduce processing power and lead to operating system errors. There are several warning signs that your CPU is becoming too hot to handle. Sudden restarts and blue error screens can indicate an overheated CPU. Before you reach for a fire extinguisher, check your CPU temperature. You can do this in a few simple steps from your computer's BIOS screen.

• 1

  Turn off your computer. After it is fully powered down, turn it back on.

• 2

  Press the "F2" or the "Delete" key on the first screen that appears after turning on your computer. Keep pressing the appropriate key until the BIOS screen appears. The BIOS on most machines can be accessed in this way. However, your computer may require a different keystroke to access the BIOS. Refer to your manual to be sure.

• 3

  Choose the "PC Health Status" option from the BIOS menu. On some machines, this may be referred to as the "System Health" or "Sensor" option.

• 4

  Note your CPU's temperature. This number can be found under the "CPU Temperature" heading. The screen also displays the temperature of your motherboard.
