4. Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot
openings at the back of the computer, before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity
that might harm internal components.
