Nothing showing up on monitor

Hey everyone,

So I just upgraded my computers motherboard and processor but whenever i start up my computer, nothing happens on the monitor.

I know it is not the graphics card, power supply, or the monitor because they all worked before I put in these new things.

The LED light on the motherboard is not turning on.

Whenever I start up my computer I can hear a single beep.

I believe all the power cables are plugged in correctly.

At first, I tried using DDR2 ram in a DDR3 slot unknowingly, but I quickly replaced the DDR2 ram with DDR3 but it still doesnt work, even when i put it in a different RAM slot.

Not sure what would cause this, but I plugged in my Razer Death Adder mouse to see if the lights would turn on and it did, but my keyboard and headset did not work.

I am only using 1 stick of 4g DDR3 RAM.

I am using and

My power supply is 630 watts which should be enough.

I am only using one graphics card.

I tried using a different DVI cable and monitor just in case, still didn't work.

Anyone know whats happening? If you need more information just ask.

Thanks in advance!
