Tips Cleaning Computer Case

There is nothing wrong with leaving spills, dirt, and stains on your computer case. After all isn't that what the case is for, to protect the electronic components inside from spills and dirt? This is true, but there are still parts of the case that need to be cleaned and checked if you want your computer to live a long and prosperous life.

Unless you like looking at dirt everytime you look at your computer, you should go ahead and clean those spills, stains, and dust off of the case. You can do this with just about any cloth and cleaner. Do not use highly abrasive cleaners that might ruin or mar the surface and do not use solvents on plastic. A wet sponge will even work. Just make sure that the cleaner or any liquid does not seep into the inside through cracks and vents. If there is any possibility that you are going to get that messy, turn off and unplug the computer first and wait to turn it back on until any liquid has had a chance to fully dry.

After you have wiped off the outside, it is time for a little inspection. Look at the blades of the fan in the back of the computer. Also look at any vents. Is there dust there? Is there a lot of dust and grime caked on to it? If so, that is an indicator that the inside also needs to be cleaned (I will tell you how to do that in next week's article - How to Clean your Motherboard).

Some clean environments never have to have the inside cleaned. Some need it cleaned monthly. When I lived in Russia, even though I didn't notice it, the air was not clean. The fan on the computer would cake up with dirt and grime after about a month of use. And so I would have to clean the fan, vents, and inside monthly. If I had let it go for several months without cleaning, the fan would have stopped working and the computer would have overheated. Where I now live in the US, the air is clean and I have gone years without having to clean it. Again, the indicator of this is the blades of the fan and the vents. If they are dirty, they need to be cleaned.

You can do some of the cleaning from the outside. First, turn off the computer. Then get out the vacuum sweeper and using the hose, vacuum out the vents and the fan(s). If you have compressed air (you can purchase compressed air from your computer store), you may want to blow air in through the vents (or intake fan if you have one) to loosen the dust and suck it out using the vacuum. If there is still dust or dirt in the vents or on the blades of the fan, you can use a Q-tip to clean them.

If you do not have a vaccum, you can use compressed air alone. Always use short bursts to avoid moisture buildup. Start with the computer off and blow into every hole and vent. Then turn the computer on and blow everything except for the exhaust fan once again.

With the case clean, your computer will look nicer and with the fan and vents cleaned out it will breathe easier and run cooler.

Definition of Computer

Meanwhile, according to webopedia, the definition of computer is :

A programmable machine. The two principal characteristics of a computer are:
a. It responds to a specific set of instructions in a well-defined manner.
b. It can execute a prerecorded list of instructions (a program).

Modern computers are electronic and digital. The actual machinery -- wires, transistors, and circuits -- is called hardware; the instructions and data are called software.

Welcome to My Commun-IT-y

Aloha.. Welcome to my IT Corner. Let's talk about computer and technology. For the first time, let me describe what computer is.
According to the wikipedia, A computer is a machine which manipulates data according to a list of instructions.

Computers take numerous physical forms. The first devices that resemble modern computers date to the mid-20th century (around 1940 - 1941), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers.[1] Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. [2] Today, simple computers may be made small enough to fit into a wrist watch and be powered from a watch battery. Personal computers in various forms are icons of the information age and are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.
The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity.
