是不是电压不稳啊？
用了UPS吗？

电源线更换过，使用了UPS。

再观察观察吧。时好时坏的。
没准是接触不良啊。

别听楼上的扯。
自己用手摸已摸，是不是电源的风扇坏了，无法散热。
我以前就碰到过这种情况，风扇坏了，不能散热，电源就停了。等它冷下来，又好了。然后再热，又停。
和LZ说的情况一样。

接触不良表现不是这样的。

有可能是这样的，机器目前的状态是，如果系统的attention灯亮的话，是黄灯在慢闪，不知道各位见过慢闪的没，然后有时会听到“吱吱”的声音，但从前侧看，电源的绿灯是亮的。我估计是电源有问题了，申请了个电源，晚上换下吧，看结果会是怎么样的。谢谢各位。

就你明白？你不也是说个半吊子么。我扯不扯管你毛事。用不着你来评价老子！

风扇不转都看不出来的话还搞个P的排错啊。以为遇到个风扇不转你就是专家了？？

这年头，有些人说话怎么就那么没有素质。。
