The inside of the computer is the most important part of the computer that needs to be cleaned. A computer case can get clogged with dust, lint, pet fur, bugs and other undesirables. Removing dust from the computer vents increases air circulation and helps to keep the system cooler and last longer.

If you don't remove the dust the circuit boards the system can slow down and over heat as the dust will interfere with air flow and circuitry connections. Allowing the system to overheat will eventually lead to component failure or complete system failure.

Supplies needed

Screw driver - to open the computer's case

Canned Air or Air Compressor

Dust Mask (optional)

Vacuum Cleaner or broom (to clean up the area afterwards)

Steps to Clean your Computer:

1. Turn off and unplug the computer. Alternatively turn off the system and then turn off any surge protectors or UPS's. The last thing you want is to shock yourself or the system while working on it. Disconnect everything connected to the computer once it is shut down. This includes things like speakers, monitors, printers, keyboards and mice.

2. Remove or open up the casing of the computer (directions should be in your computer manual or even on the back of the case). Most computers have a few screws holding a side panel in place. Some systems have a little tab or switch to open the sides. After this the panel can be simply slid off.

3. Take the computer outside or into an area you can sweep or vacuum after you are done as often a lot of dust will come out.

4. Place one hand on the outside of the case. This helps to release static electricity and prevent transfer inside the case if you bump something. With the other hand use the can of air to clean out the dust from the vents and the fan in the back of the computer.

* An alternative to resting one hand on the case is to wear a Antistatic wrist band.

5. Use the canned air or compressor to blow the dust out of the computer going in one direction while using short bursts of air. Start with the upper part of the computer and work your way down, this sweeps out all the dust that has settled on lower components all at once.

If the air causes any of the fan blades to spin, don't worry. That's harmless and actually a good way to get them clean.

* Doing a second sweep from top to bottom will ensure that all dust is removed.

* Some technicians will vacuum out the inside of a system. This must be done with great care and is not recommended.
