If you’re going to open-up your personal computer on checking some computer hardware components or for cleaning-up the hardware you must have to take these some precautions I listed. Computer motherboards and components, such as sound card, video card, and memory, contain very delicate Integrated Circuit (IC) chips. To protect computers against damage from static electricity, Anyway for brief information on what static is, it’s a major contributing factor in the breakdown of computers, eliminating the damage from ESD (Electrostatic Discharge) can save a lot of money. Here are some warnings you must remember and follow some precautions whenever you work on your computer.

1. Unplug your computer when working on the inside or well known inside of central processing unit (CPU). You must unplug the power cord to ensure that there is no power to the motherboard.
2. Capacitors can still store electric charge for a short from the time you turned off the power switch, so it's a wise to make is 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 safety grounded object or to a metal object, such as the power supply case.
4. Hold components in both edges and try not to touch the IC chips, leads, capacitors, or circuitry as these are miniature electronic components and it may 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. Remember, avoid dropping your hard disk in the surface or in the floor because cylinder of the hard disk is sensitive which may cause not to working at all.
6. Don’t ever touch the non-serviceable. When you come across labels that say "No serviceable components inside" don't take it as a challenge because it’s a serious statement. Remember some parts of a computer are just not meant to repaired which usually seen on the power supply.

Keep in mind that failure in protecting yourself can cause injuries and it can also damage your computer and the most common accident is erasing stored data (due crash board). These are simple to remember to protect yourself, software, hardware, and the most important to protect our precious stored data from our computer.
