A dirty motherboard can adversely affect your computer's performance. Dust and small bits of debris can accumulate on the motherboard, causing it to overheat and eventually fail. Periodic cleaning will keep the motherboard in optimum condition. Precautionary measures such as not smoking near the computer can help minimize dust and residue on the motherboard. Perform routine cleaning every three months to extend the life of your motherboard and keep your computer running smoothly.
