Even in the most carefully kept household, dust and dirt will find their way into and onto your computer. When dust settles onto the circuitboard inside your machine casing, the efficiency of the electrical pathway is compromised, and performance suffers. Eventually, damage occurs, and expensive repairs become necessary. Here's how to keep your computer clean and running smoothly. Take a look at your monitor owner's manual. If it specifically warns the user not to use commercial glass cleaner, it's got a particularly delicate anti-glare coating.

Turn off and unplug both the computer and the monitor. If you are going to clean the inside of the computer, disconnect the monitor, keyboard, and all peripherals. Move the computer away from them, as you'll be blowing dust all over the place.
