"1. Booting Issues
If your CPU is dead, it won’t go through the normal booting process. For instance, there will be no beep codes when you start the computer since the POST test isn’t passed. However, you might hear the fans running.
Apart from the absence of beep codes, you’ll notice a blank screen. You won’t get any response from your computer regardless of the number of times you click the mouse buttons or press the keyboard keys.
You can even confirm this further by looking at computer motherboard LEDs. If the LEDs are on when you turn on your computer but the system fails to pass the POST test, it’s evidence enough that the CPU is bad. "
