its got an AMD 3700+, Asus A8N-SLI Deluxe , nvidia 6800gs, 1gig of Corsair XMS. It all runs on a 500w Antec SmartPower.

I put the thing together today and got it all set up but when I turn it on I get a blank screen. All the fans are spinning, the cd-rom lights up, and the motherboard has its green light on meaning no errors found. Also the front led lights are lighting up even though I've made 100% that everything is hooked up correctly.

bad board maybe?
 
Do you have the right BIOS version to support that CPU?
Check on the Asus website...

The bios version that comes on the mobo is usually written on a small sticker on the top of the bios chip. What does yours say?
 
Swap for a different video card just to see? Is it that the HDD and the optical drive are POSTing or just flashing their lights? (Do they make the right kinds of noise?) Is the little speaker speaking to you? Have you tried booting with just the motherboard, video card, one stick of ram and the CPU? When will we bother to make a sticky with these same questions in it?

I dont have the latest bios but I have the bios that support my cpu.

I also tried taking everything out piece by piece to no avail.
 
take no offence to this, but do you have all three power connectors on your mb pluged in. The main one, the 4 pin, and the molex

yes
 
Is there maybe an extra motherboard standoff behind the motherboard that is in the wrong spot, causing a short? I did that once, and the computer would power on but not start up. Thankfully nothing burned out!

checked for it, didnt find anything

I read around some other forums and took their advice. I took the video card out trying to see if I could get an error beep but I got nothing.
 
Well from what I can see on the google search I did for your board, it may have onboard video. Did you try hooking your monitor to that without the video card in place? Could be it's running, but with onboard video enabled, so the image signal is being sent to the onboard VGA instead of to your video card.
 
Umm I ran into this problem with my msi neo2, it turned out to be the memory sticks were in the wrong dimms, 1 & 2 didn't work for me orignianally.

Take your memory out and boot up. If you hear a steady beeping its not the motherboard.

If you get the steady beeping, turn off your system, place ONE stick of memory in the first slot, and reboot. Exchange till it works, or until you make sure that it isn't the problem.

I tried taking the ram out and I finally got an error beep. However the beep code it gave me said that there wasnt a video card inserted. When I booted it without a video card I didnt get anything at all.
 
That's odd. Sounds like maybe a faulty mobo. When you booted with no video card, was your monitor hooked into the onboard VGA slot?

Also check your manual and see what density RAM is supported by each DIMM slot and at what speed. There may be further instructions on which slot to use first as well.

there is no onboard video
 
Did you check your motherboard manual for RAM compatibility issues?

What type of expansion slot does your video card use? PCI, AGP, or PCI-E?

If AGP, does your motherboard support 3.3V AGP cards?

If neither of those are the culprit, you might just have a faulty motherboard.
 
I just shipped my motherboard back to newegg. After reading the recent reviews it appears as though this is happening to a few people recently
