由扎实的计算机专业基础知识和基本操作技能

硬件维护

计算机硬件的维护主要有以下几点:
(1)任何时候都应保证电源线与信号线的连接牢固可靠;
(2)定期清洗软盘驱动器的磁头(如三个月、半年等);
(3)计算机应经常处于运动状态,避免长期闲置不用;
(4)开机时应先给外部设备加电,后给主机加电;关机时应先关主机,后关各外部设备,开机后不能立即关机,关机后也不能立即开机,中间应间隔10秒以上;
(5)软盘驱动器正在读写时,不能强行取出软盘,平时不要触摸裸露的盘面;
(6)在进行键盘操作时,击键不要用力过猛,否则会影响键盘的寿命;
(7)打印机的色带应及时便换,当色带颜色已很浅,特别是发现色带有破损时,应立即更换,以免杂质沾污打印机的针头,影响打印针动作的灵活性;
(8)经常注意清理机器内的灰尘及擦试键盘与机箱表面,计算机不用时要盖上防尘罩;
(9)在加电情况下,不要随意搬动主机与其他外部设备。
软件维护

对计算机软件的维护主要有以下几点:
(1)对所有的系统软件要做备份。当遇到异常情况或某种偶然原因,可能会破坏系统软件,此时就需要重新安装软件系统,如果没有备份的系统软件,将使计算机难以恢复工作。
(2)对重要的应用程序和数据也应该做备份。
(3)经常注意清理磁盘上无用的文件,以有效地利用磁盘空间。
(4)避免进行非法的软件复制。
(5)经常检测,防止计算机传染上病毒。
(6)为保证计算机正常工作,在必要时利用软件工具对系统区进行保护。
总之,计算机的使用是与维护分不开的,既要注意硬件的维护,又要注意软件的维护。
