just put together a second pc out of stuff I was going to sell on ebay. everything used was in good working order. I put the whole thing together and it won't power up, the mobo power light comes on, so that's getting power. at first I thought it was the power switch, I clipped the wires and tried to hotwire it but still no go, all the power, front panel, leads are hooked up correctly, everything else is hooked up correctly, I've gone over it several times, can't figure it out. any ideas why this won't start?
 
What kinda specs on the build? My only thoughts are not getting all the power plugs on the motherboard. I know the old s939 boards had like 3 plugs and I'd always forget one. Any diagnostic LEDs? Processor snug in?

Oh also, make sure there's some sorta plug in the CPU fan slot on the motherboard. Sometimes a motherboard won't start if it doesn't think there's something cooling the processor. I think you can change this after you get into the bios.
 
Fit a loudspeaker to the motherboard and listen for beep codes.

oops, forgot to put specs in:
asus a8n32-sli
ocz gold ddr500
opti 170 (@2.8)
8800GTS
neopower he500

cpu fan is plugged in. it is a s939, I have the 24pin and 4pin plugged in, aside from that there's the ez-plug, but I'm not using sli, so don't need that. it's weird, I just pulled this board out of other system, I was using it while I rma'd other mobo, and it was working fine. I had a similar problem with same board or maybe a8n-sli, where it just wouldn't start up, I ended up unplugging everything and putting it back together, and it started fine after that, will try that next....
 
You might try taking the mobo out of the case (in case you have something shorted out) and try again. I'd start with the minimum amount of hardware first (cpu, cpu fan, mobo). Gradually add stuff back (one at a time): memory, video, etc. You get POST code beeps early on.
 
Agreed ^^
Try another PSU possible, make sure it is strong enough first.
