家用电脑经过一段时间的使用会出故障,而且有些故障出现的频率相当高。如果一有故障就送修,作为一般家庭是很难承受的。实际上,由于计算机工作于低电压,小信号状态,真正由硬件损坏而引起故障的可能性是很小的,大多数故障发生在与外界直接交换信息的软盘驱动器,且一般为软故障,在家里即可排除。软盘插入驱动器,启动系统或读写文件时,可能出现如下故障: Home computers will fail after being used for a period of time, and some malfunctions occur at a fairly high frequency. If repaired on a faulty basis, it is unaffordable for the average family. In fact, there is a very small probability that a computer will actually malfunction due to hardware damage due to low voltage, small signal conditions. Most failures occur on diskette drives that exchange information directly with the outside world, and are typically soft faults. Home can be ruled out. When a floppy disk is inserted into the drive, the system is started, or a file is read or written, the following problems may occur:
