电脑开启故障!风扇、主板灯、电源LED灯均亮,但是显示器依然是黑的!所有连接均没有问题!

可能是你的电源 功率不够
或者就是你们住户那里本身就会电流过载导致停电
解决方法就是换个电源试试 或者买个继电器 不过那个很贵 很贵
那你可以买一个变频器,在电压低的时候你可以变频到你想要的电压。
你说的不是很详细 如果是这个样子的话。 会出毛病的 地方 是主板! 网卡一般不爱坏。显卡报警有的话。显卡坏。 没有就是主板。 我建议! 把所有的东西 都取下来。 弄点酒精擦擦。 试试。 如果单纯的按你说的这些毛病的话, 1.主板(可能行最最大,大到肯定的程度了)2.显卡 不是很确定 单从显示器不亮上 找原因。 它逃脱不了干系! 至于花多少钱。 主要是看配置了! 不过现在差不多点的 主板 400左右。 显卡 好点的也就400来块钱!但愿我说的这些都没用。。 你电脑一点事都没有!
更换电源,购买支持宽幅的电源,例如长城BTX500SE双卡王或者康舒IP470+
买个ups吧,一般买几百元的就行了,平时可以在稳压的时候自动充电,低电压时就可以正常用了。
