Processor Troubleshooting Techniques
Processors are normally very reliable. Most PC problems are with other devices, but if you suspect the processor, there are some steps you can take to troubleshoot it. The easiest thing to do is to replace the microprocessor with a known-good spare. If the problem goes away, the original processor is defective. If the problem persists, the problem is likely elsewhere.
Table 3.56 provides a general troubleshooting checklist for processor-related PC problems.

If during the POST the processor is not identified correctly, your motherboard settings might be incorrect or your BIOS might need to be updated. Check that the motherboard is jumpered or configured correctly for your processor, and make sure you have the latest BIOS for your motherboard.
If the system seems to run erratically after it warms up, try setting the processor to a lower speed setting. If the problem goes away, the processor might be defective or overclocked.
Many hardware problems are really software problems in disguise. Be sure you have the latest BIOS for your motherboard, as well as the latest drivers for all your peripherals. Also, it helps to use the latest version of your given operating system because there usually will be fewer problems.
