There are many things that can cause a
computer system to fail physically. The most common are dust buildup,
extreme temperatures, and rough handling.
How dusty or static prone the area is where the PC is placed will
determine how often it will need to be cleaned.
If a computer is not regularly cleaned, dust can build up on
the components inside the computer, such as on the fan bearings or
on the printed circuit boards. If there is a large amount of dust
buildup on a fan, it could cease operation and cause the system to
overheat. This is especially true with newer CPUs. If the
processor fan ceases to work, the computer will either malfunction
or completely shut off, and the processor can be damaged.
For these reasons, keeping the inside of the computer clean is
very important. In order to clean inside the computer case
properly, unplug the unit and move it away from other equipment.
Use a can of compressed air
, making sure to follow the directions
carefully, to blow out all of the dust within the case. This
simple process should be done at least once a year in not very
dusty areas and two or three times a year in very dusty areas.
This process will serve two purposes. By removing the dust, the
motorized components will work more efficiently for a longer
period of time. It will also keep dust from building up, which
will reduce the chances of an ESD from the dust.
Another hazard to computers that should be avoided is extreme
temperatures. If a computer system overheats, there are several
problems that can occur, such as system malfunction and data loss.
To prevent this, make sure the ventilation mechanisms of the case
are properly functioning and the room is at a comfortable
temperature.
The last thing that could cause damage to a computer is rough
handling. When moving the system from one place to another, care
should be taken so as not to loosen any components inside. If a
component becomes loose while the machine is turned off, it could
be damaged when the unit is turned back on.
