Oneupweb : Computer Maintenance—Inside The Box

Posted on in Blog

One of the elements most frequently overlooked when it comes to computer maintenance is inside the box.

Two of the most damaging elements to a computer are heat and moisture. Heat accelerates the deterioration of the heat-sink compound and delicate circuits in your systems. The most common causes of overheating are dirt and dust.

If your computer resides in a somewhat clean, climate controlled environment, you can probably get away with an annual cleaning. If your computer resides in a less desirable location, like a shop floor or a warehouse, you may need to arrange a cleaning every few months.

You will need the following supplies:

  • Screwdriver to open the case
  • Lint-free cloth and electronic cleaning solution, or wipes designed specifically for contact with electronic components
  • Small soft brush
  • Can of compressed air
  • Vacuum
  • Grounding strap

Before opening the case, be sure to turn off the power, unplug the computer and ground yourself.

The case: Never apply any solutions directly to any electronic components…ever! Spray or pour the solution on to a lint-free cloth or use electronic specific wipes to wipe the interior and exterior of the case. Pay special attention to remove dust and dirt build-up from any vents. The soft brush can be used to free difficult dust or dirt from hard to reach areas where the dust or dirt has become caked-on. The compressed air can be used to blow out the dust once free.

Inside the case: Paying close attention to the power-supply, case and CPU fans, spray these components with a blast of compressed air. In the event you have accumulated significant amounts of dust, you can use the small soft brush.

Closing up: Once the case and inside the case has been cleaned and you have reassembled the cover, it’s a good idea to vacuum any mess created. Many computer professionals recommend that you not vacuum inside your computer.

Placement: Now that everything is “spick-and-span” take a look at the area in which your computer resides. Be sure there is adequate ventilation. Note: Cold air is drawn in from the front and blown out the rear. Keep your computer away from direct sunlight and other equipment or appliances that generate heat. A standard I’ve always tried to follow has been to leave at least 6 inches on each side and at the rear to provide proper ventilation.
