我们都知道电脑有可能会出现电脑无法开机的情况,那么面对这种情况,你们是怎么解决的呢?小编也遇到过电脑无法开机的情况,那我们就束手无策了吗?并非如此,小编在打开机箱之后,就按照自己的想法去试了一试。
小编在遇到电脑无法开机的情况后,自己就按照想法在电脑主机箱鼓捣了一番,发现电脑无法开机的问题解决了,看来这套切实可行,于是,就决定把这经验分享给大家。
电脑无法开机怎么办图文解说
按下电源按钮后,显示屏无显示,电源指示灯不亮,电脑无法启动。
恢复开机(图1)
先检查连接问题,再检查配件好坏问题
显示器电源指示灯不断闪烁,说明显示器电源连接正常,再更换主机电源线,故障依旧,说明不是电源线的问题。
恢复开机(图2)
把主机电源线拔下后,打开主机机箱,将ATX电源插头拔下,重新插入主板电源插座,再开机测试。
恢复开机(图3)
如果还是无法开机,检查机箱电源开关线,发现开关线连接在主板PW-ON插针。
恢复开机(图4)
怀疑电源有故障,用一块好的电源替换原先的电源,开机测试,显示器出现了正常的开机状态,那么就是电源故障。
恢复开机(图5)
更换一个ATX电源后,安装操作系统,并使用测试软件拷机测试,一切正常,故障排除。
恢复开机(图6)
此类故障是ATX电源损坏,或主板损坏,或机箱电源开关线问题导致电脑无法开机。这类现象比较常见于旧电脑中。
第二种情况,电脑开机后,显示屏没有反应,主机电源指示灯长亮,却不能启动。
恢复开机(图7)
首先检查显示器线条有没有按接好。
恢复开机(图8)
如果按接线没问题,关闭主机箱的电源,打开机箱,检查内存条,显卡这些设备是否接触不良。
恢复开机(图9)
如果内存、显卡等安装牢固,用替换法检查内存条,假如该操作可行后,那么就是内存条那里发生的问题。更换一条新的内存条即可。
第三种情况是,按下机箱电源键后,显示器黑屏,电源灯闪一下又灭,电脑不能启动。
面对这种情况,我们首先检查主机开机电源键。
打开主机机箱,把开机电源键连线和重启键连线拔下,然后短接主板的电源开关,如果电脑可以正常启动,说明电脑的主板和ATX电源没有问题。是开机电源键接触不良导致的。
恢复开机(图10)
以上,是小编接触到电脑无法开机的一些现象而进行的操作,如果小编哪里有做的不好或失误的地方,欢迎前来告诉小编。
