Learn to do computer maintenance

Learning computer maintenance, computer users will continue to encounter many failures and problems, and because the computer user must master some basic knowledge of maintenance, which can help them diagnose most failures and work hard to solve these failures, many failures do not need to be directly handed over to computer experts Solve, for example: screen failure, slow computer, blue screen.
