did you plug in the power connector in properly? its easy to misplace the the small pins

 

[itchytoo]

yeah it looks like everthing is plugged in correctly. By the way, when I pressed the power button the first time, the fans started spinning for a mili second, but then it stopped.

 

[itchytoo]

oh and If I unplug the little pins, then plug them back in, then when I press the power button, the fans start up again but then stop after half a second.

 

[itchytoo]

okay, so I was messing around with the wires, then I got the computer to boot up! but when I tried to but the back panel on, the computer turned off, and I cant seem to get it to turn on.

 

[TheBigTroll]

what back panel?

 

[itchytoo]

the side panel at the back where all the wiring is

 

[itchytoo]

well, I finally got it to turn on, but after about 10 seconds, it just shuts off, then turns on again. I cant get into the bios.

 

[itchytoo]

now it wont turn on, same problem as before

 

[itchytoo]

when I turn on the computer, the fans, and the lights turn on for half a second, then the whole computer turns off. After that I cant even get the fans to spin if I press the power button unless I turn the power supply off, then wait till the led on the mother board turns off. Then when I turn the power supply on, I can turn the lights and the fans on for half a second. All the lights and fans turn on exert for the power and hhd leds. Help!

 

[TheBigTroll]

it could be the board....

 

[itchytoo]

everything was working when I did an external build

 

[TheBigTroll]

did you install the motherboard properly? because if you didnt you could short the board

Have you tried unplugging/removing everything except the mobo, 1 memory stick and processor?

I did that, and it worked. Then I installed everything else one by one. Everything is working now, thanks!
