Troubleshooting Microprocessors.

The Microprocessor commonly called CPU is the boss of the computer. It normally hides on the motherboard below a large heat sink and often a fan assembly as well. The dudes that make these cool guys normally name them like car companies name their automobiles, they get a make and model e.g. Intel Core i7, AMD FX-8350 Black Edition. When it comes to Microprocessors, there is a duopoly, Intel and AMD control the market. So if you want to find out about the latest CPUs make sure you check out:
Other cool websites to check out in case you are thinking about an upgrade or hunting for the latest CPUs are:

Also, note that a CPU goes into a CPU socket on the motherboard. The thing is motherboards are manufactured with various types of sockets hence you'll need a techie to help you with which socket goes with which CPU family.

CPU headaches normally fall into two broad categories: overheating and catastrophic failures, with overheating being the more common.
Common symptoms of overheating are lock-ups and shutdowns once the PC is put under any form of load (this could range from as simple as booting to trying to run an application) due to a built-in fail-safe in the CPU that tells it to shut down before it gets damaged. Most times this overheating is caused by faulty installation, or a broken down or clogged heat-sink/fan assembly. Since a CPU requires zero insertion force when installing, issues with installation normally stem from:
  • ·         Putting too much thermal paste which impedes the flow of heat from the CPU to the heat sink causing the CPU to heat up rapidly.
  • ·         Not enough thermal paste or thermal paste that is spread unevenly that causes the CPU to heat up and consequently shut itself down.

Also once a PC starts overheating, a likely cause is the heatsink/fan assembly. Check that the fan power is connected to the motherboard, and make sure that it is functional. A fan that is not functioning will cause the CPU to heat up and shut itself down.

A catastrophic failure presents itself with a Blue screen of death which is technically called windows stop error. On a Mac OS X, you'll get a wheel on the screen that doesn't just go away or stop spinning.  In some cases, the entire system will stop and go blank and you might perceive the smell of burnt electronics. If you smell something burnt, open the case of the PC and sniff to check if the smell is coming from around the processor. If it is then what caused the short most likely hit other components on the motherboard and you’re definitely looking at a lot of replacements.
