for the processor than on the original motherboard would cause the processor duct to be unable
to provide effective processor cooling. For this reason, the Thermally Advantaged Chassis
(TAC) Design Guide, which replaces the CAG, no longer includes this recommendation.

Processor Duct” in Chapter 3 of

entirety on the disc packaged with this topic.
Because a thermally advantaged chassis is much better at cooling for little extra cost, I highly
recommend that you look for these features on the next system you buy or build.
Processor Troubleshooting Techniques
Processors are normally reliable. Most PC problems are with other devices, but if you suspect the
processor, you can take some steps 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 3.30
provides a general troubleshooting checklist for processor-related PC problems.
