I just built my first computer, but it seems when I turn it on the computer powers up (fans and lights) but quickly turns off in what seems like half a second. I understand how to build the motherboard, so I believe I put everything in the right place, after it was doing this I took everything out and put it back in to no avail. The only lights I see turn on is a blue light with the words "Multi BIOS" on the motherboard near it, and a light for a little box that says "Audio Boost." When there is power to the motherboard there is a green power button that lights up, a reset button, and an overclock button. The CPU fan, graphics card's fans, power supply fans, and some case fans I connected all spin.
Hopefully someone will be able to help. I've searched around and couldn't find anything to help me. I hope I've given enough information for someone to figure out why it's doing this, if not then I'll answer any questions about it.
Standoffs?

Do you mean something to raise the Motherboard off the case a little?

Yes, sounds like something is shorting out.
I've had this happen to me when I built my new compy. It turned out that the processor socket didn't match with the motherboard socket. (1156 is my cpu I KNOW ITS SHIT and 1155 was the mobo I KNOW I SHOULD HAVE GOTTEN A DIFFERENT PROCESSOR LEAF MEH ALOWN)
Worth double checking.
I raised the motherboard and it still doesn't work, and I know I have the right processor and motherboard, I made sure when I bought it and I checked again.
I applied the compound stuff on the CPU, could it be that the fan's stuff isn't doing to good with the stuff I put on?
You could have fried the mobo when you didn't have the mobo standoffs installed, which may be why it still doesn't work
Also, list your components
Oh and about the thermal paste, most heatsink/CPU combos you buy as one package (I.E stock coolers with a CPU) will have thermal paste already applied to the heatsink. Putting more on would be detrimental unless you cleaned off the old stuff (or if there was none there already) however it probably wouldn't cause it to turn off so suddenly

If I fried the motherboard shouldn't it not be lighting up at all? I sure hope it isn't fried, will I need to buy a new one, or is there a way to make sure it is fried?
There's no hard and fast way to tell, what motherboard is it?
It would not hurt to check to see if the RAM is tightly in. My PC used to continually boot repeatedly when the RAM is not fully in when I installed my RAM upgrade.

Damn, that's an expensive oops.
I can only suggest removing the motherboard from the case and trying to power it up on a non-conductive surface. Aside from that, you may have the heatsink mounted improperly.

It doesn't change when I move it onto a non-conductive surface. I took the CPU fan off and wiped off the compound and took out and put back in the CPU and it didn't work.
Why would you put the heatsink back on without thermal compound?

The fan? I didn't, I left it off.

IT'S WORKING! Apparently I forgot to plug in the 8-pin CPU for power.
Thanks for everyone's help though!
Man we really need to start reminding people to check that first.

Why is it so common to not plug in the CPU power when it's like playing a child shape game? You see the square pegs on the board and the same pegs from the PSU, you'd think most people would just plug it in for the hell of it.

No offense, James0roll.

Well that plug was hiding kind of in the corner of the motherboard, I assumed it'd be powered because it was in a socket on the board, but I was wrong.
I'm actually writing this on my new computer! Went from 430 GTX to 760 and ditched Vista for Windows 7! :D
