Prevent this with a handy black and yellow grounding wrist strap from Syba (SY-ACC65030). Tighten on the grounding bracelet and clip the other end to a proper grounding surface (like your PC's case) and the harmful static your body naturally builds up will be channeled harmlessly away, leaving your motherboard, memory, and other component free of harm! If you're planning on doing any work around naked PC parts invest in this wrist strap today.
