You should always bench test a system first. Look at this.

Tear it all apart & start from scratch. What power supply do you have?

bench tested system, no joy! Only one stick of ram, no hdd, fdd, or dvd drive on board. Keyboard lights flash when first turned on, then nothing.

Well, you're down to a bad psu or mobo. I would bet the mobo.

Did you boot up using a video card ? Which one, and how many amps on the +12V rail for the psu ?

Booted up with no video card, using onboard hdmi port. when I remove the ram, I get 1 long beep and 2 short beeps. No other sounds. Could it be the ram?

"I have a new "Power up" LT 400w atx psu"

It's a cheapie & not a goodie. Not enough amps on the +12v rail for a modern system. You should have no problem benchtesting with it, provided there's nothing wrong with it:

Are you sure the CPU & heatsink are installed correctly? Make sure you don't have a mouse connected to the board & use a PS/2 keyboard, not USB. Why are you using the HDMI port for testing? If your monitor has VGA or DVI, try one of those instead. When you attempt to boot, do the cooling fans come on & stay on, or do they stop? Also, did you try booting without any RAM installed? The board should beep like crazy.

I aligned the cpu properly, No mouse connected, ps/2 keyboard, I'll try vga port next. When I power up, the cpu fan comes on and stays on, have not installed case fan yet. When I boot without ram, I get a series code of one long beep and two short beeps that repeat. Case power and reset lights and buttons work.

I used vga instead of hdmi to my monitor and still no joy> Ram is in the correct slot for the board. Still stumped!

"without ram, I get a series code of one long beep and two short beeps that repeat"

The fact that you get beeps is a good sign. 1 long + 2 short = graphics failure, do you have a video card you can try?

Not on hand, but I'll get one. And, a big thanks to all for the help!

By the way, the only time that I get code beeps, is when I remove the ram completely. Any ideas?

Is it possible that the on board video is turned off by default in the bios?

No, but it wouldn't hurt to use the Clear CMOS jumper to reset the BIOS defaults. BTW, do you have the 4-pin ATX12V plug connected to the board just behind the HDMI port?

I did reset the cmos jumper but same result. I also have the 4 pin molex connector on the atx cpu board connection. I'm going to check out the power supply next.

Thanks again to all! I tried resetting the cmos one more time as a last resort, and viola! it's working.
