使用过电脑的小伙伴应该都遇到过这样的问题,那就是明明按了开机键,但电脑还是毫无反应。要不然就是听到了主机启动的声音,但就是毫无显示。这该如何是好呢?接下来,小编来就来告诉你电脑开机没反应该怎么办。
最近小编在逛网页的时候看到比较多小伙伴反映的一个问题就是电脑开机没反应,于是小编我就研究了一下这个问题。现在我已学有所归,那么接下来就很迷们分享分享我所研究出来的解决方法!
首先,检查一下电脑主机是不是能正常通电。然后再看电源板供电是不是正常,再检查机箱电源有没有启动,如果启动了的话,可以看到电源风扇正常转动。

如果是电源没有启动,那就看看机箱电脑开关在主板上的排线是不是松动或者排线损坏了,可以用小的金属短接主板上的两根电源开关针。电源启动了话,考虑开关和排线是不是出了问题,如果还是没有启动的话,再看看电源或者主板有没有问题,可以更换电源或者送专业的维修中心来解决问题。

如果机箱电源正常工作了,但是CPU风扇还是没有反应,那可以试一下给主板放一下电,断开电源,取下主板上的CMOS电池,过一分钟左右,等主板上的电放完后,再扣好电池,开机重试。

如果CPU风扇正常工作了,但是电脑还是没有正常开机,那就要看看内存与内存槽是不是接触不良。可以先断开电源后,再拔下内存条,用橡皮檫或者干净的白纸来擦拭金手指,直到金手指上没有污点,用干净的毛刷刷一刷内存槽,用气吹仔细的吹一下,再插好内存条。

如果CPU风扇工作正常,并且内存也正常,通过正常启动时,有“嘀”的一次响声来判断,显示器却还是无信号输入,那就要看一下是不是显卡接触不良或者损坏,可以先断开电源,然后取下显卡,把金手指处擦拭干净,用气吹吹去插槽的灰尘,然后装回显卡,再开机。

如果还是没有解决的话,看看是不是连接显示器的VGA接口损坏或者VGA线损坏,然后可以更换一根VGA线。

如果以上的方法还是没有解决,那就要拿到专业的维修点进行维修啦~~~
