How to clean your Mother Board

If you have not done the inspection mentioned in the previous article – How to Clean your Case, now is the time to do so. Look at the blades of the fan in the back of the computer. Also look at any vents. Is there clusters of dust there? Is there grime caked on to it? If so, the inside needs to be cleaned. If the fan blades are clean but it has been several years since you have cleaned the motherboard or if the computer is around cigarette smoke, it probably should be cleaned anyway. Dust and particles in the air (like cigarette smoke) can build up on the circuitry of the motherboard and cause it to heat up and/or corrode.

The first thing that you need to do is unplug your computer. Then open up the case to get access to the motherboard. Cases open differently. If you don’t know how to open your case, look on the back of your computer along the edge for some screws. These screws may hold on side panels or an upside down U shaped panel that covers the sides and top. Removing the screws will allow you to take off the cover. Other cases have the screws on the front of the computer. To get access to these screws, you must first remove the front panel by pressing a hidden latch. The cover is there to give easy access to the inside of your computer, so if you look hard enough, you should be able to figure out how to remove it.

Remember that if you touch anything on the motherboard, you should be grounded by either touching the metal frame of the computer with your other hand or by wearing a special grounding device.

The goal of cleaning the motherboard is to remove all dust and debris from the motherboard and all components inside of the case. This can be done using one of three methods.

The preferred method is to use a can of compressed air to blow it out. Always hold the can in an up-right position to prevent the propellent chemicals which can damage or corrode components from coming out. Dust and dirt should be blown away from the motherboard and out of the case.

Another way to remove dust is to use a vacuum. The common advice is to only use a battery operated vacuum because an AC powered vacuum causes static and static can ruin the motherboard. I have used an AC powered vacuum (before I knew that it was not recommended) to clean my motherboard many times and it has never caused any problems, but I may have just been lucky. When using the vacuum, keep the nozzle a couple of inches away from the motherboard or any other components so that it does not come in contact with them and so that any small parts are not sucked into the vacuum.

If you do not have a can of compressed air or a vacuum, you can use a dry cloth and brush to clean the motherboard. Be careful not to dislodge or break anything using this method.

While cleaning the motherboard, be careful not to unplug any cables or connections or to dislodge any loose components, such as, jumpers.

Methodically clean the whole inside of the case going over all of the motherboard from one end to the other and all other components. Don’t forget to clean the fans and heat sinks. Do not open up the power supply box or stick anything in it beyond the fan. If you do, you could get a shocking surprise and ruin your computer.

If your computer does not work when you put it back together, something was obviously dislodged during the cleaning. Open the case back up and push all connections and cards into their slots. Look for anything that may have become disconnected.

Cleaning the motherboard is probably the most dangerous form of cleaning but it is necessary to prevent an early death of your computer.

How to Clean your Keyboard

Posted by lapantz4less on May 6, 2008

Written By: Ray Geide

When it comes to cleaning your keyboard there are many methods that can be used, some harder and more effective than others.

The easiest method is the Shake Method. It is so easy that you can do it right now. Pick up your keyboard, turn it over being careful not to press any keys, and shake it. See all of that stuff fall out? It is dirtier than you thought, isn’t it? You can use one of the following methods to clean it further.

The Blow Method – You can buy cans of pressurized air at the computer department or computer store which are made especially for cleaning your computer. They usually have either a hose and nozzle or a tube extending from the nozzle. Hold the keyboard up vertically (that means that end of the keyboard is up and the other end is down), aim towards the keys and press the button. Keep blowing until all of the debris is blown out. Be sure to get around and in between all of the keys. This can be done with the computer on, but it is better if it is off so that you do not have to worry about pressing the keys and coming up with a page of aaaaaaaaaaaaaaaaaaaaa’s.

The Vacuum Method – This is just like the Blow Method except that a vacuum is used instead of a can of pressurized air. It is quite simple. Just turn the vacuum on, pull out the hose, and run the nozzle over the keys. Before doing this make sure your keyboard does not have any loose pop off keys that could be sucked into the vacuum.

The Cotton Ball Method – This can be done in addition to the above methods and in lieu of the following methods. Take a cotton ball or cloth and wet it with rubbing alcohol. It should not be so wet that the alcohol runs down into the cracks of the keyboard. Wipe the tops and sides of the keys.

The Dishwasher Method – I hesitate to tell about this method because there is the possibility that it could fry your keyboard. When I had less experience with computers, I dunked my keyboard in a sink full of water to clean it. It did work afterwards, so I don’t doubt those who say this method will not mess up your keyboard, but if it does, don’t complain to me. I warned you. If your keyboard is not the standard membrane type of keyboard or if it is on a laptop, do not even think of trying this.

This is how you do it. Unplug the keyboard and place it face down in an empty dishwasher. Do not disassemble the keyboard and do not put it in a dishwasher that has dirty dishes in it. Some say to add soap, some say not to. Run the dishwasher through a regular cycle. Take the keyboard out, shake the water out, and stand it on end until it is completely dry (this may take several days). If it does not work after doing this, it may not be dry. Let it stand another week and try it again. If it still does not work, I warned you.

The Disassembly Method – This is the most thorough method, but it should not be done on laptop keyboards or non-standard non-membrane keyboards.

Turn off the computer and unplug the keyboard. Turn the keyboard upside down. You may want to get two books or short boards to place the keyboard on. Position them so that they hold up the keyboard on the edges when it is turned over. This should leave the keys dangling and not touching the books or the floor. This is especially needed when the keyboard’s back is off; otherwise the keys will be lifted out of their position by the floor (or whatever surface it is laying on).

Get a screwdriver and remove all of the screws from the back of the keyboard. Lay the keyboard down on the books and carefully remove the back.

Take everything apart and clean thoroughly. It is better to take the keys out one at a time and clean them so that you do not put them back in the wrong place. Wipe each one down with a wet cloth and then with a dry cloth. Any keys that may be hard to put back in, can be cleaned in place without removing them. Wipe around the keys as they sit in place and blow any debris out with your lungs (using compressed air or a vacuum may upset the keys). If you are really brave, you can remove all of the keys at once and give the frame a good wipe down too.

Do a once over and make sure that you have cleaned everything. Then reassemble it all.

Don’t forget the keyboard’s cable. Wrap a wet cloth around it and wipe it down. It may have an accumulation of grime that needs to be scrubbed off. Also if any of the letters on the keys have rubbed off, you can use a fine point permanent marker to draw the letter back on the key.

Use these cleaning methods and your keyboard will last a long time and be something you can be proud of.

Symantec Norton Antibot The Latest In Norton Computer Protection Software

Posted by lapantz4less on May 6, 2008

It seems like every other month a new “program” comes along to make our lives that much easier. For example, first we could bookmark favorites, and then RSS feed them, and then came widgets and now “bots” which are robots that do a lot of our computer work for us in the background. Examples of friendly bots are weather bots, game playing bots, instant messaging and my favorites are those on AOL Instant Messenger which do all kinds of functions for me like shop, find movie times and even give updates on the Wall Street Journal.

Unfortunately not all bots were created “equal.” Some are friendly and some are not. The ones that are not friendly can be a form of malware that allows control of your computer to be released, providing hackers with the opportunity to access your information and spread harmful bots to others. This type of computer virus can then be used to spread spam and commit various types of identity theft and other online fraud.

So with new threats to our computers and information, new methods of protection are required. One of the oldest and most well known software protection designers has recently released a new protection program, Symantec Norton AntiBot. This is a software product designed to prevent the hijacking of one’s personal computer by bots and uses the bots on design programs against them, to located and destroy them.

Many people already employ some form of protection on their personal computer, such as increasing the protection level from internet information to “high.” But these cannot detect some of the most recent bot programs and may not be the most efficient means of information protection, especially with the Internet being used more and more frequently for online shopping, ticket purchases, travel and other “high risk” activities.

A more effective method of detecting and eliminating threats caused by bots is to install software designed specifically to detect, destroy and prevent bots from having access to your computer. With Symantec Norton AntiBot software, protection against bots is enhanced several times and the threat of bot attack is greatly diminished. It’s program protects against bots by blocking bots from entering your computer through downloads and e-mail attachments (two of the common ways bots enter a personal computer), checking for any unusual behavior on your personal computer and eliminating it, and detecting malicious bot software at all levels; keeping your personal, financial and credit card information safe and stopping identify theft before it can occur.

Because bots operate in the background and are not detectable by antivirus or antispyware programs, many computer users are completely unaware that their personal computer has become infected. Many problems caused by bots go undetected until it is too late. Warning signs that your computer may have been accessed include: slowness of computer speed and unusual or irrelevant error messages. However, many times com these symptoms are sporadic and computer users will take little notice. Many people will continue to use their personal computer, unaware that bots have hijacked their personal computer and are slowly at work; looking for credit card numbers, passwords, and logon information which can be used for identity theft and in committing other types of online crime. This program scans your personal computer on a continuous basis, closing the gaps that could allow bots to infect your personal computer and better ensuring that bots do not invade and gain control.

The use of Symantec Norton AntiBot to determine what a harmful or useful bot and allows you to continue using those bots you love and have come to depend on for information and services. It can be used in addition to several other antivirus and antispyware programs. Its compatibility is not limited to only Norton products.

The cost of this software is $29.95 for one year of service. It was awarded PC Magazine’s Editor’s Choice Award (2007) and underwent rigorous testing which included using AntiBot on computers with existing threats as well as allowing threats to try to access the computer after installation.

With the growing threat of identity theft and credit card fraud Symantec Norton AntiBot offers an additional level of protection needed to combat the threat of bots and prevent them from turning one’s personal computer into a robotic that turns into an instrument of destruction to both your personal and financial well-being.
