很多人都遇到过电脑开不了机的情，其实电脑无法启动的原因有很多种，谁遇到这个问题都会觉得比较棘手。只要弄明白问题是由硬件还是软件引起的，逐一排查原因，就能很快解决问题。下面一起来来分析一下电脑开不了机的原因。
近期发现不少电脑用户在问这个问题，大部分使用电脑的朋友应该都遇到过电脑无法启动，并且对这种情况也是束手无策。其实造成电脑开不了机原因有很多，如系统损坏、中毒、硬件发生故障等等，下面，小编就为大按键提电脑开不了机的一些原因和解决的方法。
电脑开不了机怎么办图文教程
首先查一查是否为电源连接或者是电源自身的问题。尤其是主板24Pin接口以及CPU供电线接口，一定要插牢固。

短接电源无需通过主板开机就能让电源运转，这同时能够检测一台电源是否正常运行。方法很简单，只需将24Pin接口上的绿线口和任意一个黑线口短接就可以。如果不能运转(风扇不转)就是证明是电源的问题了。
有一种情况是主板灯亮，说明电源有输出，但是还是无法启动，这个需要排查的东西比较多，但首先没有进入主板开机自检，有可能是开关键以及BIOS的问题。

机箱的I/O区域位于顶板的前端，方便了用户的操作。机箱的I/O区域拥有开机/重启按键都通过跳线与主板连接。主板的跳线针脚对于小白来说连接是比较困难的，连错了就会造成主机不能开机。首先可以检查跳线连接是否正确。尤其是power sw线一定要连接正确。

跳线接好后仍然无法启动，可使用改锥等工具短接启动针脚。
如果能启动证明可能是跳线开关有问题，更换即可。

BIOS重置可以手工调整或者是直接扣电池来实现。如果不亮的话就需要直接扣电池试试了。扣掉主板上的纽扣电池，15秒之后再装回去，就可以实现BIOS重置。
会听到“滴”的一声，但是如果发出蜂鸣声或者一直在“滴....”的声音，一般都是出现在内存条与主板内存插槽接触不良造成。只要用橡皮擦来回擦试其金手指部位即可解决问题。当然，主板上的内存插槽坏了这也是有可能的。

内存问题首先检查下内存有没有插紧。再者可能是主机积灰过多造成内存短路，可以先吹一吹内存插槽附近的灰，待清理干净后再用橡皮擦拭内存条的金手指。
