电脑时好时坏,显卡风扇不转,显示器黑屏无信号的解决办法:

  1. 电脑安装独立显卡需要看显卡插槽是否兼容,显卡供电是否满足输出;

  2. 电脑时好时坏,显卡风扇不转,显示器黑屏无信号,可排查电源显卡供电是否连接好,显卡供电不足显卡是无法正常运行的;

  3. 可重新插拔显卡的外接供电,或者更换大一点功率输出的电源看是否有所改善;

  4. 独立显卡优先使用直连输出,转接输出会影响信号不稳定,或者可使用带芯片的主动式转接头转接输出;

  5. 内存条接触不良或者是内存损坏也会间接导致显卡输出无信号,显卡性能缺失,可重新插拔内存条或者更换内存插槽看是否正常;

  6. 可使用替换法把显卡放在其他主板上使用,排查显卡的硬件故障,如为硬件故障可联系售后处理。

CPU与插座接触不好,重新拆装下CPU即可,再有就是内存,也是接触的原因。

擦下内存金手指。顺便显卡也擦下。再有就是拆下主板电池。短接电池座,清零主板CMOS设置。要是硬件没坏,就两个原因,一个就是各部件接触不好。自检不过。卡在那里。再有就是灰尘的原因,可能积累静电,导致启动失败。

最好有DEBUG卡,看跑码,卡在哪里不走了,就是哪的问题。前几天帮同事整过,也是黑屏风扇转不启动,插DEBUG卡,走到58不动了。重新拆装CPU搞定。单位办公室的电脑也是这样。各种拆,清洁,擦金手指。一样手到病除。

自动黑屏之后显示器指示灯,以及主机电源指示灯的状况,这样才有利于分析和判断;
一、显示器
1、黑屏之后,(显示器)指示灯随之熄灭,表明显示器自身故障,一般是电源部分有问题;
2、黑屏之后,指示灯长亮(不闪烁),表明显示器的高压板(包括它的供电电路)、背光灯电路、AD驱动板电路有故障;
3、黑屏之后,指示灯闪烁,不一定是显示器的问题;
二、主机
1、显示器黑屏之后,主机面板上的电源指示灯同时熄灭,表明主板、主机电源有问题;
2、黑屏之后,主机电源指示灯长亮,但显示器出现第一项第1、2条,表明显示器有问题,而出现第一项第3条则有可能是主机电源、主板、显卡、信号电缆,或显示器有问题;
3、黑屏之后,主机电源指示灯闪烁,一般是主机电源的问题,也有可能是主板的问题;
但从“必须按重启才能继续”这一点来看,主板的可疑度较大。

呵呵,楼主估计的不错,看来也是高手啊,呵呵。

电源的问题不像,如果电源供电不足多一半是电源有问题,要是电脑是比较老了,有可能出现这个问题
显卡问题也有可能,如果你显卡风扇的电源是在主板上那就查主板,如果在显卡上面就把显卡放在别的电脑上面试一下,显卡应该没有什么问题。这种问题多出在主板上面。你可以试一下。。

把电脑上面只用硬盘、主板、cpu、内存(内存如果是两条的话只留下一条)、独显加显卡,集显就不加显卡,组装好以后开机测试,看一下电脑显示不显示,主板bios界面,如果不显示,把bios初始化,或者把主板电池,扣下来在不同电的情况下按开机键,在把电池插座短接一下,然后再开机,看一下
如果主板问题不大应该能解决如果不行就是这些部件有不兼容或者损坏,需要更换新配件。

希望能帮到楼主。

最大的可能就是你机器内部受潮了,如果机器点不亮,我建议你那吹风机朝机箱内部吹烘下,或者直接拿到太阳下面晒一会,但不要长时间晒,看看效果如何?
我朋友的机器找不出毛病,我就是这样干的,结果真的是受潮的原因
