      Troubleshooting processor issues - Desktops

      To troubleshoot processor issues, follow these steps and test the processor after performing each one:

      Notes:
      • If either the system board or processor have been replaced, reflash the BIOS to the latest level before proceeding.
      • Some computers allow the fan to stop spinning. This is not a malfunction. The fan should start spinning as the system heats up.
      1. Ensure the latest BIOS code is installed. This will correct any 167 POST errors for the Intel microcode update and "176 No Processor CPUID" post errors.
      2. Reseat the processor and the heat sink

        Note: Do not touch either the processor or system board contacting surfaces. These can be extremely fragile and bent pin damage due to touching is not covered under warranty.
      3. Verify the processor fan operation is not blocked by cables or other hardware.
      4. Verify that any replacement processor is the correct architecture for the system.
      5. If these steps have not solved your problem, refer to "Need more help?"
