New computer won't start

[moondoggie]

Hello, I assembled it all, and plugged it in and it fired up for about 2 seconds, beeped, and shut off. What should I do?

Unplug, Then Go Through All Of The Connections One At A Time. Maake Sure They Are All Secure And Safe.

Hmm. I had a problem like this, and it did exactly the same thing. Hopefully this is the issue as its simple.

Look for a connector coming off the power supply called the ATX 12V connector (A wide connector with a load of pins)

If there is a space for it on the motherboard, plug it in and it'll power up like nothing happened.

I hope this helps.

That's connected, I don't know what's the matter. Arrgggghhh!

make sure that the reset wires from the front pannel are in the correct place, as well as all of the other pins from the front pannel.

They are. I know everything is in the right place, I checked everything at least 10 times each. It's just not working.

I wouldnt doubt that you're current was set to either 225 and ur in the US or 115 and ur in EU. Make sure you're psu is set to the right voltage.
If this is the problem, you probably fried your psu.

Oh and make sure that the CPU Heatsink and fan are installed correctly

what sorta beeps you getting, and which mobo is it ... using this we can decode the beeps

This is the mobo http://www.newegg.com/Product/Product.asp?Item=N82E16813170147 and it turns on for about 3-4 seconds, then while running, it beebs for about 1/2 a second and shuts off, but i don't think the psu is fried, because the front led lights are still on.
