No Power To Motherboard

[Telsiph]

Greetings all,

I continue on my struggles to get this new computer working. It is absolutely driving me nutts, and I am hoping some might have some insight on what I could try. I recently purchased a

and

As the motherboard. I have a 10K RPM Hard Drive (raptor), 4 sticks of 240 pin 1 gig sticks of RAM, and a 650 Watt Power Supply that are used from my old computer. Once I put the computer together I found that nothing happened when I hit the power button. No beeps, no fan turns, nothing. I continued to test with a different computer and found that the power supply worked fine, as did the 8800 GTX video card, and the hard drive. I took all sticks of RAM out, still got no power, and put 1 stick of RAM back in, and still got no power. I assumed it was a DOA motherboard as I do not see how a bad processor would cause the entire motherboard to not even turn on, so I RMA'd the motherboard. They were out of stock, refunded me, and I then purchased a

To upgrade it a bit and ensure this didn't happen again. Well it just arrived today, and upon putting the computer together I find that the *exact* same problem remains, I see no evidence of any power going through the motherboard. The motherboard has 2 onboard "power on" and "reset" buttons, as well a BIOS code indicator that seems to me, should get power and turn on if the motherboard was getting power. I am unable to get this motherboad to turn on either, and I am wondering if maybe it is the processor ( which is going to put me in a real bind as I've had it for almost 2 weeks now dealing with all the back and forth shipping ).

I know the power supply works as it works on my other computer, but I do not have a spare intel processor to test the motherboard with, so I am unable to change out the processor for another processor, or the motherboard with another motherboard to test either of them. I have taken out all of the RAM, and still nothing happens when pushing the on-board "power on" switch. Any insight on further tests I can do to ensure it is the processor, or to get it working would be very appreciated, as I am having difficulty believing that I was shipping 2 different DOA motherboards, and I am going nutts trying to figure this out, thanks!

Are you sure the PSU works?

Yes, I tested the PSU on an older system running a AMD single core processor. The system is a lot weaker, but 650 watts should be plenty to run the system. It was able to power the system, and I ran Age of Conan on it for a while to guarantee that it ran properly. I have just recently tested the system by unplugging everything except for the 8800 GTX (which I know works as I also used it during the test on the older system), 0 sticks of RAM (and then 1 stick of RAM later on), the ZALMAN fan plugged in(and then not plugged in), and the PSU. All power connectors were plugged in (24 pin, 6 pin secondary, and tertiary video card power to the motherboard. Plus the additional 2 power cables straight from the PSU to the video call). All tests provided the same results, no power. No lights, no code, nothing. It's absolutely infuriating.

Bit of an update as I continue to test. I read thread
http://www.tomshardware.com/forum/245237-30-help-bought-evga-680i-mobo-wont-turn

Which seemed to have a similar issue, though not resolved. I stripped the system down to the 8800 GTX video card, the 650 watt power supply, the ZALMAN CPU Fan, and the quad-core processor. I ensured that the 24-pin ATX power connector was plugged in (the power supply has a 24-pin connector. Although the older computer I tested it on only had a 20-pin motherboard, is it possed the extra 4-pin are broken in some way, and thus it can't power a 24-pin motherboard?). The 8-pin ATX_12V power connector is plugged in (firmly) as well. The AUX PEX power connector is also plugged in. 2 PCI-Express power connectors are plugged into the 8800 GTX, and the ZALMAN is plugged into the CPU-Fan slot on the motherboard. There is no RAM, and I am still unable to get anything. No information on the display, no beeps, nothing. The switch on the power supply is obviously on, and as I stated on my older AMD Motherboard the 8800 GTX, and the power supply work fine. The power supply is a

I have no found any posts that lead me to believe a dead processor can keep a motherboard from turning on, or receiving any power at all, which is why I'm testing so many things before RMA'ing it. I suppose there is the tiny chance I was sent another DOA motherboard, but it seems unlucky. Any information would be appreciated!

did you hook up the leads from the case power button to the mother board properly, it can be easy to get them backwards
