Opening your personal computer to clean up hardware or check some of the components can be dangerous to its health. Motherboards and components such as memory, video cards, sound cards, and hard drives all contain small Integrated Circuits which are very susceptible to Static Electricity. Static Electricity is the spark you see when you touch a doorknob after walking across the floor. The problem with static electricity is if you touch a component in your computer when your body is charged up then there is what is known as an Electrostatic Discharge (ESD) across the components. ESD causes pitting of the surfaces of the components which may not cause an immediate failure but can lead to failure in the long term and cost a lot of money in replacement costs. Below are some precautions to follow as well as tips to remember when working on your computer.

1. After turning off the computer, unplug the power cord to make sure there is no power to the motherboard.

2. Since there are capacitors in the computer which can store a charge for short periods of time, it is a good idea to wait a few minutes after unplugging the power cord before working on the computer.

3. Get a grounded wrist strap from an electronics supply house and connect it to a ground before handling the parts, such as memory, video card, modem, hard drive, etc, inside your computer. If a grounded wrist strap is not available then touch a safely grounded object such as a metal pipe to discharge any static electricity that may have built up on your body.

4. Hold components by both edges and try not to touch the IC chips, leads, capacitors, or circuitry as these are miniature electronic components and may be damaged.

5. Place components on a grounded anti-static pad or on the bag that came with the components whenever the components are separated from the system to prevent static discharge. Remember, avoid dropping your hard disk because cylinder of the hard disk is very sensitive and it may never work again if dropped.

6. Dont ever touch the non-serviceable. When you come across labels that say “No serviceable components inside” don’t take it as a challenge because its a serious statement. Remember some parts of a computer are just not meant to repaired and this label is usually seen on the power supply which isn’t a good idea to try to repair. Replacement is best.

Remember that you are responsible for protecting yourself from injuries and from causing damage to your computer. A common incident is loss of stored data due to a hard drive crash. These are some simple things to remember that will protect you, your computer and most of all the data stored on your computer.
