The graphic card is one of the most important pieces of hardware in your PC. Without it, your super monitor with all the bells and whistles is just a junk box.

Make Directional Input

Most video cards come with simple frame capture programs, but you'll have to do some programming if you plan to integrate video capture with other operations on your computer, such as adding text data as an overlay or changing video-in channels on the fly. In this case you'll need good programming libraries in a language with which you are familiar for the video card. Some companies include libraries with their cards, but most charge extra. Most often libraries, when available, are for C or BASIC, and sometimes Pascal.

Choose Between 24 bit and 32 bit

For True Color mode, some graphic cards offer 24 bit while some offer 32 bit. Which is the best? When True Colour mode was first suggested, it utilizes 32 bit which was very pleasing to the eye, they realize that 24 (with less coolers) won't look much different since the human eye can only take about a certain amount of colors. On the other hand, 24 bit will run faster compared to 32 bit because it uses less colors. So if your card utilizes 24 bit, don't worry, it isn't bad.

Always Use The Latest Drivers

Yes, it is important to make sure you always have the latest drivers. The latest drivers will offer you better performance, more utilities and more compatibility (usually for DirectX or Direct3D). Take the effort to check you card manufacturer's site to look for the latest driver updates.

Why? Flatbed scanners commonly become dirty with dust, fingerprints, and hair. When a scanner is dirty, the images may have distortions.

Procedure: Clean a flatbed scanner's surface by spraying a window cleaner onto a paper towel or cotton cloth and wipe the glass until clean. As mentioned earlier, never spray a liquid directly onto the component.

To clean the outside of the scanner, the same towel or cotton cloth can be used.

Why? Cleaning the outside of a printer can help keep the printer's appearance looking good; and in the case of a printer that is used by many different people, keep the printer clean of germs.

Procedure: First, make sure to turn off the printer before cleaning it. Dampen a cloth with water or rubbing alcohol and wipe the case and each of the buttons or knobs on the printer. As mentioned earlier, never spray any liquid directly onto the printer.

Why? With some printers it may be necessary to clean the inside of the printer to help keep the printer running smoothly.

Procedure: Because of numerous types of printers, different steps in cleaning printers, and printer manufacturer policies on cleaning the inside of the printer, we recommend you obtain the printer cleaning steps from your printer manufacturer.

Why? Dirty touch screens can cause difficult navigation.

Procedure: To clean the Palm Pilot Screen, use a soft cloth moistened with rubbing alcohol and rub the screen and the casing of the palm pilot. It is not recommended to use glass cleaner as it could damage plastics over time.

Why? A dirty optical-mechanical mouse (mouse with a ball) can cause the mouse to be difficult to move as well as cause strange mouse movement.

Procedure: To clean the rollers of an optical-mechanical mouse, you must first remove the bottom cover of the mouse. To do this, examine the bottom of the mouse to see which direction the mouse cover should be rotated. As you can see in the below illustration, the mouse cover must be moved counter clockwise. Place two fingers on the mouse cover and push the direction of the arrows.

Once the cover has rotated about an inch, rotate the mouse into its normal position, covering the bottom of the mouse with one hand and the bottom should fall off including the mouse ball. If this does not occur, attempt to shake the mouse gently.

Once the bottom cover and the ball are removed, you should be able to see three rollers located within the mouse. Use a cotton swab, your finger, and/or fingernail and move in a horizontal direction of the rollers. Usually, there will be a small line of hair and or dirt in the middle of the roller, remove this dirt and/or hair as much as possible.

Once you have removed as much dirt and hair as possible, place the ball back within the mouse and place the cover back on.

If the mouse still appears to be having the same issue, repeat the above process; if after several attempts the mouse is still having the same issues, it's likely that your mouse has other hardware issues and we recommend that it be replaced.

Note: Cleaning your mouse pad with a damp cloth can also help improve a computer's mouse movement.

Why? To help keep a mouse clean and germ free it can be helpful to clean the mouse.

Procedure: Use a cloth moistened with rubbing alcohol or warm water and rub the surface of the mouse and each of its buttons.

Why? Dust and especially particles of cigarette smoke can build up and corrode circuitry causing various problems such as computer lockups

Procedure: Our recommendation when cleaning the Motherboard from dust, dirt, or hair is to use compressed air. When using compressed air hold it in the up-right position otherwise it is possible chemicals may come out of the container that could damage or corrode the Motherboard or other component within the computer. Also ensure when using compressed air that you always blow the dust or dirt away from the motherboard, or out of the case.

Another good alternative to compressed air is to use a portable battery powered vacuum that can effectively remove the dust, dirt, and hair from the motherboard completely and prevent it from getting trapped within the case. However, do not use a standard electricity powered vacuum as it can cause a lot of static electricity that can damage the computer. When using the vacuum it is vital that you stay a couple inches away from the motherboard and all other components to help prevent contact as well as to help prevent anything from being sucked into the vacuum. Ensure that you do not remove any small components with the vacuum such as jumpers.

Why? Dirt, dust, and fingerprints can cause the computer screen to be difficult to read.

Procedure: The glass monitor screen can be cleaned with ordinary household glass cleaner*. Be sure to remove power from the monitor and spray the cleaner onto a lint free-cloth so the fluid doesn't leak into the electrical components inside the monitor. Vacuum off any dust that has settled on top of the monitor, and make sure no books or papers have been placed on the air vents. Obstructed monitor vents can cause the monitor to overheat or even catch on fire.

*Warning: We suggest using a cloth dampened with water when cleaning monitor on a screen that is not made of glass or has any type of anti-glare protection on the screen. Using ordinary household glass cleaner on special screens, especially cleaners with ammonia can remove anti-glare protection and/or other special surfaces.

Why? Dirt, dust, and finger prints can cause the computer screen to be difficult to read.

Procedure: Unlike a computer monitor, the LCD / flat-panel display is not made of glass, therefore requires special cleaning procedures.

When cleaning the LCD screen it is important to remember to not spray any liquids onto the LCD directly; do not use a paper towel as it may cause the LCD to become scratched.

To clean the LCD screen we recommend that you use a soft cotton cloth; if a dry cloth does not completely clean the screen, you can apply rubbing alcohol to the cloth and wipe the screen with the damp cloth. Rubbing alcohol is actually used to clean the LCD before it leaves the factory.

If you're trying to clean a laptop keyboard see document CH000780 for additional help and information. All of the below information applies to standard desktop computer keyboards.

Why? Dirt, dust and hair can build up causing the keyboard to not function properly.

Procedure: Many people clean the keyboard by turning it upside down and shaking. A more effective method is to use compressed air. Compressed air is pressurized air contained in a can with a very long nozzle. Simply aim the air between the keys and blow away all of the dust and debris that has gathered there. A vacuum cleaner can also be used, but make sure the keyboard doesn't have loose "pop off" keys that could possibly be sucked up by the vacuum.

Why? If the keyboard has anything spilt into it (ie: pop, Pepsi, Coke, beer, wine, coffee, milk, etc.), not taking the proper steps can cause the keyboard to be destroyed.

Procedure: Below are a few recommendations to help prevent a keyboard from becoming bad once a substance has been spilt within it.

If anything is spilt onto the keyboard turn the computer off immediately. Once the computer is turned off, quickly flip the keyboard over helping to prevent the substance from penetrating circuits. While the keyboard is upside down, shake the keyboard over a surface you do not mind getting wet or that can be cleaned up later. While still upside down, use a cloth to help clean out what can be reached. After you you have cleaned the keyboard to the best of your ability leave the keyboard upside down for at least one night allowing it to dry.

If a keyboard does not work after trying it again later it is recommended that it be replaced. If the keyboard works but some of the keys are sticky or cannot be pressed in you can attempt to do additional cleaning in attempt to resolve the issue. Unfortunately many times when any sticky substance such as a non-diet pop is spilt directly onto the keyboard it's usually a loss unless you plan on spending dozens of hours attempting to clean each key.

Why? A keyboard that is used by multiple people, such as students or different employees, may need to be disinfected to help the spread of germs.

Procedure: Turn off the computer. Spray a disinfectant onto a cloth or damp a cloth with alcohol and rub each of the keys on the keyboard. As mentioned in our general cleaning tips, never spray any type of liquid onto the keyboard.

Why? While hard drives cannot be cleaned physically, they can be cleaned with various utilities on the computer to help it run fast and more efficiently. Utilizing these utilities will prevent the hard drive from slowing down.

Procedure: Refer to our basic troubleshooting section for your operating system for steps that can be done to help improve the performance of your computer.

Why? Headphones that are used by multiple people may need to be cleaned frequently to help prevent the spreading of germs and head lice.

Procedure: If the headphones being used are plastic and/or vinyl, moisten a cloth with warm water and rub the head and earpieces of the headphones. As mentioned earlier in our cleaning tips, it is recommended that if your headphones are being used for a library or school that you do not use any type of disinfectant or cleaning solvent as users may have allergic reactions to the chemicals they contain.

Headphones that have cushions also have the availability of having the cushions replaced. Replacing these cushions can also help keep the headphones clean.

Finally, in regards to headphones and the spreading of head lice, if multiple students are using your headphones, you should consider having the students use their own headphones, using bags that are placed over the headphones, or having headphones that can be wiped with warm water after each student has used the headphones.

Why? Dirty read/write heads on the floppy drive can cause errors during the reading and/or writing process.

Procedures: The floppy drive can be cleaned two different ways. The first method of cleaning a floppy drive and our recommended method is to purchase a kit at your local retail store designed to clean the read/write heads on your floppy drive.

The second method of cleaning the floppy drive is only recommended for experienced computer users. Open the floppy drive casing and physically swab the read/write heads with a lint-free foam swap soaked in pure alcohol, free-on, or trichoroethane. When performing these steps be extremely careful when cleaning the heads to ensure that you do not lock them out of alignment causing the floppy drive to not work. To help prevent the heads from becoming out of alignment use a dabbing motion lightly putting the swab on the head and removing it, do not perform a side-to-side motion with the swab.

Why? Dirty CDs can cause read errors and/or cause CDs to not work at all.

Procedure: Cleaning CDs and DVDs should be done with a cleaning kit but can also be done with a normal clean cotton cloth or shirt. When doing this with a clean cotton cloth or shirt, wipe against the tracks, starting from the middle of the CD or DVD and wiping towards the outer side as shown in the below picture. Never wipe with the tracks; doing so may put more scratches on the disc.

It is recommended when cleaning a CD that water is used. However, if the substance on a CD cannot be removed using water, pure alcohol can also be used.

Why? A dirty CD-ROM drive or other disc drive can cause read errors with CD discs. These read errors could cause software installation issues or issues while running the program.

Procedure: To clean the CD-ROM drive we recommend purchasing a CD-ROM cleaner from your local retailer such as a local Radio Shack. Using a CD-ROM cleaner should sufficiently clean the CD-ROM laser from dust, dirt, and hair.

The plastic case that houses the PC components can be cleaned with a lint free cloth that has been slightly dampened with water. For stubborn stains, add a little household detergent to the cloth. It is recommended that you never use a solvent cleaner on plastics.

Make sure all vents and air holes are hair and lint free by rubbing a cloth over the holes and vents. It is also helpful to take a vacuum around each of the hole, vents, and crevices on the computer. It is safe to use a standard vacuum when cleaning the outside vents of a computer, however if you need to clean the inside of the computer, use a portable battery powered vacuum to prevent static electricity.

Although many companies have created products to help improve the process of cleaning your computer and peripherals users can also use household items to clean their computers and peripherals. Below is a listing of items you may need or want to use while cleaning your computer or computer peripherals.

Keep in mind that some components in your computer may only be able to be cleaned using a product designed for cleaning that component, if this is the case it will be mentioned in the cleaning tips.

• Cloth - A cloth is the best tool used when rubbing down a component, although paper towels can be used with most hardware we recommend using a cloth when ever possible.

• Water or rubbing alcohol - When moistening a cloth it is best to use water or rubbing alcohol. Other solvents may be bad for the plastics used with your computer.

• Portable Vacuum - Sucking the dust, dirt, hair, cigarette particles, and other particles out of a computer can be one of the best methods of cleaning a computer. Over time these items can restrict the airflow in a computer and cause circuitry to corrode. Do not use a standard vacuum as it can generate a lot of static electricity that can damage your computer.

• Cotton swabs - Cotton swaps moistened with rubbing alcohol or water are excellent tools for wiping hard to reach areas in your keyboard, mouse, and other locations.

• Foam swabs - Whenever possible it is better to use lint free swabs such as foam swabs.

Below is a listing of general tips that should be taken when cleaning any of the components or peripherals of a computer as well as tips to help keep a computer clean.

1. Never spray or squirt any type of liquid onto any computer component. If a spray is needed spray the liquid onto a cloth and then use that cloth to rub down the component.
2. Users can use a vacuum to suck up dirt, dust, or hair around their computer on the outside case and on their keyboards. However, do not use a vacuum for the inside of your computer as it generates a lot of static electricity that can damage the internal components of your computer. If you need to use a vacuum to clean the inside of your computer use a portable battery powered vacuum designed to do this job.
3. When cleaning a component and/or the computer turn it off before cleaning.
4. Never get any component inside the computer or any other circuit board damp or wet.
5. Be cautions when using any type of cleaning solvents, some individuals may have allergic reactions to chemicals in cleaning solvents and some solvents can even damage the case. Try to always use water or a highly diluted solvent.
6. When cleaning be careful not to accidentally adjust any knobs or controls. In addition when cleaning the back of the computer if anything is plugged in make sure not to disconnect any of the plugs.
7. Never eat or drink around the computer.
8. Limit smoking around the computer.
