用户在日常使用笔记本电脑过程中经常会碰到的故障,这不,有用户在使用笔记本的过程中,就遇到了,自己的电脑按完开机键后,黑屏,没反应,无法开机的现象。接下来我们就来看看电脑开机黑屏没反应怎么办的解决方法，大家一起来看看吧。
1、首先排查显示器，把机箱的显示器VGA/HDMI线拔下来，显示器的开关打开，看看屏幕上是否有图标显示，如果有类似下图的小方框在屏幕上游动，说明显示器没有问题。
2、看主机里的电源盒是否出现故障而导致电脑断电。用螺丝刀拧开机箱螺丝，拆开盖子可以看到电源盒。拆开盖子可以看到电源盒。用镊子连接电源24针中的黑绿两根线，看看电源的风扇是否正常运转，正常运转排除电源故障，如果风扇不转或者转速很慢 ，应该是电源出现故障了，需要换电源。
3、排查内存故障，把内存条取下来用橡皮擦拭金手指，同时用毛刷清理插槽内的灰尘，之后重新插好。查看电脑是否正常开机，如果还不行的话还可以把内存换一个插槽进一步排查。
4、排查硬盘故障，一般这时屏幕上多会有英文提示，“找不到硬盘”“系统无法读取”等。如果是连接线出故障，就需要换一条线即可。这时电脑屏幕上就会显示：A disk read error occurred Press Ctrl+Alt+del to restart”
5、查看显卡故障，把显卡取下来，擦拭金手指和插槽。有独立显卡的电脑，记得连接线要和独立显卡连接否则连接到集成显卡上也会导致电脑不开机的。这种情况多见于搬家之后，需要把线拔掉之后重新安装。
以上就是电脑开机黑屏没反应怎么办的解决方法啦，希望能帮助到大家。
