启是否能进入操作系统，换？如是，那就是主板计时电池没电了？如能，进去看一下时间是否乱
时间不乱啊,就是突然黑屏了,出现一堆英文字母,需要按F1,然后就出现那个界面了它出现的很随机,不知道什么时候出来
如果时间不乱，那就不是主板没电了。但是这样显示应该还是硬件问题，至于说很随机，就说明这个故障不是固定的，属于接触不良。自己动手能力强，可以插拔硬件（不要一下子都插拔，今天一件，开机看问题是否解决）。
还是不太懂。。。
不明白，就找个明白人看看吧。

这是华硕的开机选择界面，看你的参数没问题啊，直接选退出就可以启动了，注意USB不要插U盘或手机
这个是电脑主板自带的检测软件，你还是先退回之前的界面在发个图片看看吧！
这不是进入bios了吗。。。可能是系统损坏吧。。
你这个是主板的问题
