Ok i just built a computer and it won't boot up.
My Motherboard has this beeping green light when i turn it on but fans in my computer won't turn on, cpu fan doesn't turn on, and no boot up when i turn it on. Its dead silent
Gotta figure out problem to decide to return my CPU, motherboard, memory, and power supply.

what im running:
Amd Phenom 3x
motherboard: asus m3a76-cm built in videocard until i can afford a 4770.
Memory: 4 gig Patriot ram ddr 800
Cool Master 500 watt power supply

Any help would be great.

Beeping green light? Could you elaborate on this a little more?

ex. beep, beep, beep, <pause>, beep, beep, beep, <pause>...etc.

-or-

ex. <constant beep>

Check your motherboard manual in the troubleshooting section for the list of beep codes to narrow down your problem.

The green light is the SB_Power thing on the mother board that lights up constant. no beeps.

SB_Power = Standby Power

When you press your case's power switch, does the light turn off? Do any other lights like the case's power light turn on? How can you be sure that your computer is turned on?

Make sure your case's power switch cable is plugged in to the correct pins on your motherboard. If it is, try flipping the connector around to reverse its polarity. I know, I know, it's just a switch and polarity shouldn't matter but I've encountered a few cases in the past that have a diode built in to the switch that prevents reverse polarity connections.

Thanks that fixed the problem, but it was the case wiring that was screwed up. I used another cases wiring to get it to work next to case with the new parts. Too bad the other case is falling apart.

No it was a case that I had 3 years ago. Now getting another used case from a uncle to use. I could care less about the look of a case and happy it doesn't have all those crappy flashly lights that I see on new cases.
