![]() ![]() Be aware, there are some joke screensavers out there that look like a broken screen. You can tell is an LCD screen is cracked because the crystal mess will still be visible when you turn the power off on the machine. You’re now in the market for a new monitor or laptop because a broken LCD is usually not fixable. If you break an LCD screen like this, it’s toast. If the casement is cracked or broken, the crystals will break out of their mold, causing a metallic “spilling” that will distort the monitor. Generally, there is no way for dirt to get in between the pixels on a modern monitor. Electric signals pass into the crystal, which activates the individual pixels to make the screen work. In a modern LCD monitor, which is probably what you’re viewing these words on right now, the pixes are made by an intersecting lattice of liquid crystals that are poured between two very thin sheets of plastic. By changing the color of the dots in a specific order, the computer can generate an image. A pixel is a very small dot that lights up at a particular color. Once you get large caked on pieces of dust, they can damage a computer when they break off.Ĭomputer screens generate images through the use of pixels. The key to cleaning a computer fan is to do it pretty regularly so that there isn’t any buildup. “Duster” gas can be dangerous if inhaled in concentrated amounts. Make sure that the area you are cleaning is well ventilated. These “dusters” can be used to clean electronics and optical equipment. Additionally, the gas has been filtered so that there are no particles in the can. They contain a special gas that is designed to leave no residue on electronics. Be careful with these cans, they are not really “air”. They usually have little red extension straws that can be used to maneuver around small places. These can be had for only a few dollars at any big box store. You’ll need to purchase a bottle of “canned air”. The good news is that it is very easy to clean a computer fan. Very rarely, dust in a fan can catch fire and destroy the machine. The fan can stop, or a short circuit can occur. These fans can gather huge amounts of dust. The point of this is to remove excess heat from the system. Most computers have small electric fans that blow air over the microcircuitry. ![]() But how can a regular person clean a complex machine like a computer? The most common item you’ll want to physically clean is the fan. If it moves, it will eventually accumulate dust and grime.
