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. Capacitors can still store electric charges for a short time from the when you turned off the power switch, so it is wise to make to wait a few minutes after pulling the plug before working on your PC.
3. Use a grounded wrist strap before handling computer components such as the video card, memory, hard disk, and etc. if you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case to prevent a discharge from your body to the component.
4. Try not to touch the chips, wires, capacitors or circuitry by holding circuit boards by the edges to avoid static discharge damage.
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. Never, ever open items labeled as non-serviceable. Components labeled "No Serviceable Components Inside" are not a challenge because opening them up could lead to serious injury. Some parts of your computer just aren't meant to be repaired. The power supply is one such item and should be replaced if defective, don't attempt to repair it.
Keep in mind that failure to protect yourself can cause injuries and it can also damage your computer and the most common accident is erasing stored data (due to hard drive crash). These are simple things to remember to protect yourself, software, hardware, and most important to protect our precious stored data on our computer. - 16928
