Computer Dust

Today computers are becoming as common as a telephone, they can be found in your house, office, or other various locations. Over time these locations collect dirt and dust buildup, and although it is a tedious task to clean eventually someone will vacuum, dust, polish etc. In my case, if I am lucky enough to convince my teenage children to pitch in it makes the workload that much easier. The television screen will get wiped down to remove the dust and give a clearer and sharper picture. When cleaning a computer monitor make sure it is turned off and always spray the cleaning solution on the cloth and not directly on the monitor. Eyeglasses cleaner works well.Computer-Dust

Personal computers (PC) (desktops, not laptops) attract dust like a magnet. They have both intake and outtake fans that help circulate air through the system. However dust also is being drawn into the PC and not all of it is being expelled from it. So over time the inside of your PC can collect large amounts of dust to the point it can become a serious detriment to your system.

Today’s computer systems with their large processors, video graphics boards and other components can reach temperatures over 50 degrees centigrade. Now that is hot! With the accumulation of dust, fans are not cooling the system as they should be. This in turn can make the parts overheat and eventually fail or even burn out. Replacing a central processing unit (CPU, the brains of the computer) is expensive.


So my recommendation is as follows:

  • At least every 2 months or so, (or right now if it has never been done before),
  • Disconnect the power supply cord from your PC,
  • Remove the screws from the rear of the PC to remove the side cover. (The side cover to be removed is the one furthest from the power connector and other cable connections)
  • Preferably use a compressed air canister (that can be purchased from your local computer retailer) and blow all the dust and grit out of your system. Pay extra attention to areas where the fans and heat sinks are located; this is where the majority of dust builds up.
  • Replace the side cover, reinstall the screws, and power cord.
  • Now you’re good for another few months.

Although not as effective (except for a commercial air compressor), alternatives, are a vacuum, hair dryer (set on cold air), or a large air compressor (do not exceed 40psi or you can damage various parts).
