如何判断电脑哪个硬件坏了?
展开全部
1:无显示,但指示灯亮,或风扇转,有来电的现象 ·········处理器和主板
2:无显示,但指示灯不亮或风扇不转,无来电的现象 电源+主板(电源为重点)
3:无显示,有来电,主机有滴滴滴叫声 ````·········内存、显卡、(通过叫声节奏判断具体谁坏了)
4:有显示,进系统,无声音··········································声卡
5:有显示,进系统,无网·············································网卡
6:有显示,有黑白英文显示····无法进系统·······················硬盘
7:无显示,开机需要等待会,有进系统的声音··················说明是 显示器
以上现象不能说明是坏了······需要先确定是否接触不良(很多时候是这样)
先学会系统逻辑分析 你才会用到检测卡···非专业不用花这钱(不贵)这是电路维修人员事先判断故障线路的利器。
