关键词：计算机硬件；故障分析；维修方法。
Abstract：The first computer in February 14, 1946 has come out, with the rapid development of computer and the world with the rapid development of the computer. Computer World has changed the attitude towards life has changed people's living habits, and change people's vision for the future. Computer in the military, medical, work and life have occupied animportant position, the computer also affect the development of military, medical, work and life. High-tech computer products, electrical appliances belonging to the particular, he has a characteristic that is most vulnerable to problems of production technology. Computer assembly and maintenance of computer technology in the area occupied an important position can not be ignored. Not only do we have to learn to use computers and, more importantly, when computer problems arise when there are repairs in a timely manner to maintain the peace, the paper is to move our hands to understand the basic components of computer and a number of properties, real This is the most basic grasp the most basic computer knowledge! The use of computers in the future when skilled operation!
