hard ware problem

[gohand]

I had a new build system it was running well for almost a week, but today after a half hour of using it, it just collapsed and can boot up anymore, it seem like the problem with the mobo i think, it tried unplug the power and try to boot it again, but the lights of the fan just flashed for 2/1 second then disappeared, even unplug the cpu(before i build it , power 'or the lights' stay on even unpluged cpu) do anyone ever experienced this, please help, thanks in advence!

 

[bla!!]

Does it beep at all when you boot?? Or just sit there and do nothing?

Try making sure that the memory is seated all the way into the slots.

Then try isolating the problem with booting with only the processor attached. Then add a hard drive, then a cd drive etc...

all seem good cause it is currently running, it is like run out of power suddenly and can't boot it back up, but it don't seem like there are completely out of power, cause once un/plug back, tried to boot it, the fan's light flashed less than a second.
