Power but no boot

Putting together a new computer tonight but it won't boot. When you flip the psu switch the fans come on and the hdd spins up for a couple secs then off (which I thought was odd but I've only owned thermaltake psu's previously) and the front lcd with the temp probes comes on for a few secs too. Then press the case power on switch and nothing.

List of parts:
case: http://www.newegg.com/product/product.asp?item=N82E16811146038
gpu: http://www.newegg.com/Product/Product.asp?Item=N82E16814130082
cpu: http://www.newegg.com/Product/Product.asp?Item=N82E16819115030
mobo: http://www.newegg.com/Product/Product.asp?Item=N82E16813128059
odd: http://www.newegg.com/Product/Product.asp?Item=N82E16827136120
psu: http://www.newegg.com/Product/Product.asp?Item=N82E16817139001
ram: http://www.newegg.com/Product/Product.asp?Item=N82E16820211174
hdd: http://www.newegg.com/Product/Product.asp?Item=N82E16822148230

Yes, the ram is seated corrently. Yes, both 4-pin power and 24 pin power are both connected to mobo. Hard drive is connected to first sata spot. I tried running with both roms, then one, then none. I checked to make sure the gpu was seated correctly. I double checked the connections for the pw switch, and reset switch. I'm guessing I'm going to have to take it out of the case and try it?

yea u could have gotten a bad mobo which isn't rare
 
Typical solution/test... Remove everything, start over again. Do things one by one and try to eliminate any bad components. Try with the mobo, cpu, and PSU to see if you get a no ram beep...

Should I pull it out of the case to do so?

I rest a board on about a half dozen retangular pencil erasers above a non conductive surface usually with supply, video card, memory, cpu, and maybe one fan plugged if needed if the view of the cpu fan is facing away. New boards also see a green led indicating power if you remember to turn on the breaker switch on the supply.

One other thing to note is what happened on the last build here when swapping the supply out. Nothing with the new supply? It was a simple task to unplug and lightly replug the 12v cpu feed back in that suddenly saw the system fire right up! A loose contect in the plug itself was all it was there. Just a thought on this. You can read that in the thread seen at http://www.computerforum.com/80790-bad-board-simply-need-replug.html
 
New news. I have this setup outside the case now. Mobo is powered. Cpu fan plugged in. Case pw switch connect. No ram, no gpu. < with all that the psu fan spins and nothing else happens. With ram, the same thing. With ram and gpu the mobo makes a HIGH pitched long continuous beep after I hit the case switch but fades and at the same time the psu fan slows down almost to a stop but then comes back and so does the beep. I took out the ram, left the gpu. Same annoying beep. Took out the ram and gpu again, same results as the first time with only psu fan spinning. Put the gpu back in and got the high pitched beep. I'm a bit confused about what all this means? bad gpu, mobo, psu? I find it odd that without the gpu the psu fan slow and start intermittenly but runs continuously without the gpu after the case power switch is pushed on. Is the psu to blame?

Edit: about the 12 volt connector at the top that PC Eye mentioned. i was very gently and only pushed till it clicked. i went ahead and tried reconnecting it. same results.

Hmm... Sounds almost like something's bad... This beep I assume is from the PC-Speaker and not the PSU or something?

Do you have anything else you could test the components in? Specifically the power supply, or another PSU to try in the new system.
 
The high pitched beep is certainly coming from the gpu. I would have to take the psu out of this computer if i wanted to try another one.

Edit: there is no pc speaker or mobo speaker.
 
Well you were able to rule a few things besides cpu and board. A bad video card generally sees a long and two short beeps. Or that can also be memory depending the bios. I don't like a constant beep since that often points at the cpu. On some older boards you would also see a cpu failure message instead of any audio alert or could be a bios checksum error.

The error code chart for Intel boards lf that is the same as seen in your sig are seen at http://www.intel.com/support/motherboards/desktop/sb/cs-010249.htm
 
This is not like your regular beep. THIS IS REALLY HIGH PITCHED and coming from the GPU. It also comes and goes with what seems like power loss; you know that fading sort of effect.

do gpus have low power alerts? cuz it says on newegg that it requires at least a 400w psu and idk if urs is to low
 
If you are sure it's from the card you have your answer. They probably put their flat and tiny speaker to let you know if the vpu is bad. Have another video card to throw in?

Corsair 520 can power 2 GTX's. It's not all about wattage but amperage too.

I don't any spare pc parts laying around only cables of sorts. I'm really suprised that the gpu would be DOA since it's EVGA. I guess I have my answer though? Also confused why it did not make the beep earlier-yet the fans still did the whole spin, slow down, speed up thing.

just making sure cuz I saw on another forum that somebody was having a problem with the same card is ur video card plugged in to the psu?
 
I dunno what I did but I got it to boot. Everything is plugged in except the HDD and DVD-rom drives.

hmm now in the case is the next test

Not quite. After it tries to boot, it obviously can't cuz I have no hdd connected. I decided to go ahead and try out of case with the hdd now. Now I am getting the exact same results as when I was first trying to get it to boot in the case. I tried each connection at the psu (being that it's modular) and got the same results across each time = that the fans would come on and spin for a few secs but stop and black screen.
 
It would be a shame to see a bad card but you still have a return to vendor option since you just got it in. On the new build here the board quit after 3 days. On the old Socket A I went through 3 cards there plus a sound card to add to that.

The other thought would be a bad slot on the board itself? Know someone who loan you a card to test that idea out?

Well I got the boot screen now somehow? I took everything apart and reconnected. I probably missed something somewhere. Whatever the case, the gpu must be okay if the bootscreen comes up right? Perhaps it's the hdd?
 
No hard drive will stop the initial post screen. You would simply see the failure to find boot device message after the post unless the drive had a direct short of some type pulling power down hard.

The thing that comes to mind about the card is the possible need for the power plug. On the large vpu model cards some require the extra power feed being a small plug. The 7950s are the higest DX9 NVidia models.
