Troubleshooting Processor Issues

Processor issues can appear in different ways, as illustrated in Figure 3.25.

The following measures can help you solve CPU issues:

  • The number-one issue related to processor problems is heat. Ensure that the fans work. Fans are cheap devices compared to replacing a processor or motherboard. Ensure the computer has adequate circulation/cooling. Vacuum any dust from the motherboard/CPU. Cool the room more.

  • Many BIOS/UEFI screens show the CPU temperature. (This is covered in more detail in Chapter 4.)

  • Research any visual codes shown on the motherboard LEDs or listen for audio beeps as the computer beeps. Refer to the computer or motherboard manufacturer website.

Processor issues and determining whether an issue is a CPU or motherboard issue are some of the hardest things to troubleshoot. When your video port does not work, you can insert another video card to determine the problem. However, diagnosing processor and motherboard issues isn’t so simple. If you have power to the system (that is, the power supply has power coming out of it), the hard drive works (try it in a different computer), and the monitor works (try it on a different computer), then the motherboard and/or CPU are prime suspects.
