Troubleshooting the Processor ]
It is suspected that the processor may be exhibiting problems relating to heat
Explanation: The processor seems to be overheating, causing various problems with
the operation of the system.
Diagnosis: Insufficient cooling is
probably the number one cause of problems related to processors. Newer processors depend
upon cooling devices to ensure that they are kept at correct operating temperature, and if
allowed to exceed this value by a great deal, can malfunction in all sorts of strange
ways. The sensitivity of the processor to this depends a great deal on what type it is.
- Test the temperature of the processor. Leave the machine running for an hour. Turn it
off and unplug it, then open it up. Touch the processor, or its heat sink near where it
attaches to the processor. If it feels very hot, especially if it is hot enough that you
cannot leave your finger on it for more than a couple of seconds, the processor is
probably running hotter than it should be.
- Consult your motherboard manual and double-check all the jumper settings for the processor.
Make sure it is set to the correct type and speed. Make sure the processor is supported by
the motherboard. Make sure the processor is inserted correctly into the board.
- Verify the voltage requirements for the
chip, and make sure they are set properly. Providing too much voltage to the CPU can
- Make sure you are using an appropriate cooling
device for your processor. If you are using a Cyrix 6x86, make sure you use a heat
sink and cooling fan designed for it.
- Check your CPU fan to make sure it is still turning and ensure that it will not be
obstructed by cables or hardware when the cover is put on the case. Make sure it is not
dirty. If it is old or looking worn or close to failure, replace it with a good quality
ball bearing fan.
- There are many other parts of the system that can overheat. These can affect other
components by increasing heat in the overall system. For example, a system case that has
improper cooling air flow can increase the temperature of the processor by improperly
venting the exhaust from the CPU fan. Look here for
troubleshooting information in general on overheating.
- If you do not have heat sink compound
between the processor and the heat sink, the heat sink cannot do a good job of cooling the
- Increase your processor cooling level. Some typical ways to do this include using a
cooling fan if you weren't before, using a stronger fan, or using a larger heat sink. You
can in some cases also install additional fans in the case that blow on the processor, but
this is generally overkill.
