including fans with CPU, video card and power supplier, but black screen,
indicated no signal. I changed a video card, it is the same. any one know
what happened. it worked well last night, but could not start today.

I think the first thing you should try is to change a monitor, not a video
card.

发帖数: 109 | 4 thanks for your reply, I replaced the monitor, but it did not work either.
the monitor can work with other computer too, so it is not the monitor
problem. it is very strange, if it is the motherboard, the fans should not
work.

发帖数: 165 | 11 some advice:
Firstly check whether computer starts or not. How do you connect to the
internet? If you use a router, check it there. Sometimes the pci-e slot dies
and thus no video output but the computer actually starts fine.
If the computer doesn't start, try removing all memory sticks. Insert one at
a time, try all possible ram slots to see whether you can post or not.
Good luck! |

发帖数: 109 | 12 thanks, I will do this soon when I get a new power supply, but the power
indicator is lighted, and all fans are working,so I have difficulty to
figure it out.

发帖数: 109 | 13 Thanks for your advice, the power can turn on, can you tell me what is the
relationship between router and pic-e slot.
I will take off the pci-e video card to use on-board video out to check if I
have any signals.

我上次也是这样的情况，查了下，内存条换道槽就好了。

发帖数: 10288 | 20 估计是主板上电容坏了。症状和我以前自己装的一台 core 2 duo E4500 一样。
我后来去ebay买了几个电容，费了不少劲，换了，好了。
主要是焊下来太费力了。
