gwatts :
I've got a very strange failure on a new EX58 UD3R. All components are new. Corsair 650W, the EX58, i7 2.66 GHz, 3 crucial 2 gig sticks. Stock cooler on the i7.
Upon power, the speaker "clicks" (the sound it might make if you just applied a DC voltage to it), all LED's in the CPU meter on the mobo come on full, all the fans start up (CPU fan, etc.). It stays this way for about 3 or 4 seconds, and then it powers down. About 3 or 4 seconds later is repeats the power up attempt. This cycle will continue forever without me ever having to touch the power button except for the first time.
I've tried removing the memory, reseating the CPU, and the behavior is identical. The problem has to be the mobo, power supply, or the CPU. I can do trival test of the power supply (i.e. swap in a new one at 400W, which should be good enough for this sort of test), but I have no idea how to do any further testing of the mobo or CPU to sort out which of those two is causing problems.
Suggestions for debugging? I'm new to i7 and GB - is this mobo more likely to have failed than the CPU (seems to make sense).

Hello everyone,
I registered for this forum account just so I can respond and tell you my success story! Thank you gwatts for sharing your experience.
I will start by saying this: Stay away from Gigabyte motherboards.
Here WAS my setup that I purchased a couple of weeks ago:
Gigabyte UD3R motherboard
Pentium i7 920 processor
BFG Tech GeForce GTX 260 Maxcore OC video card
OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM 1600
OCZ Stealth Stream Power supply 700W
SAMSUNG LightScribe Support - OEM CD DVD Burner
Seagate SATA 500GB Barracuda hard drive
SMC Networks Wireless 54Mbps PCI Card
CM Storm Case
Viewsonic 22" 1080p monitor
This is the first computer I've ever built on my own. I would say I have above average computer skills, like everyone else here on Tom's Hardware.
This build worked fine for 11 days. It worked great, in fact. I was playing Call of Duty 4 and Bioshock with no problems.
Yesterday, I pressed the power button and in horror I had the exact same experience gwatts had. I had no idea what to do, so I got on my laptop to search for this issue.
When I powered on my PC, all the fans would spin, and the LED lights on the Gigabyte motherboard would light up. There was no beep, rather a soft clicking sound coming from the PC speaker. There was no BIOS and no video display. The PC remained on for a few seconds, then reset itself, and repeated the same process over and over again.
I searched online for methods to troubleshoot this problem. I removed everything except for the CPU and one stick of memory. Still no beep. I removed the memory, so it was just a CPU and motherboard. When I powered on, all the fans and lights stayed on and nothing happened. It no longer reset itself.
I inserted one stick of memory and started the PC again. This time I waited a minute. There were continuous short beeps, which the Gigabyte manual indicates is a power supply error.
No way! I thought.
Fortunately, I purchased all my parts at Micro Center, which in my experience is the greatest place to build your own PC. The prices are the same and sometimes cheaper than New Egg - more importantly, you can drive to the store and interact with PEOPLE to get any problems solved, and you can touch and feel any item you wish to purchase. Micro Center has an EXCELLENT exchange policy. If just about any new product is defective in 30 days, you can exchange it for the same part. They also have an amazing protection plan. For up to 2 years I can exchange ANY part for ANY reason up to the cost of $1000. So at the end of 2 years, I'm gonna upgrade everything for FREE! For you west coast people, I hear Micro Center is the Fry's of the east coast.
So with this Micro Center confidence, I bring my parts for exchange. By process of elimination, I figured it was either the motherboard or CPU that was broken. I brought them in and without any hassle they let me exchange my i7 920 for a brand new one. They also let me return my crappy Gigabyte UD3R in exchange for the superior ASUS P6T - all I had to do was pay the difference of ~ $30!
So I go home with a new CPU replacement and a motherboard with a far superior reputation over Gigabyte.
I'm 97% sure the problem was the motherboard. The ASUS P6T was only $30 more, and is better in EVERY way over the Gigabyte UD3R. Just look at the specs. It even has higher quality Ram clips!
When you guys look at the configurations on this forum, you should notice that many of us were using 1600 Mhz memory sticks, which the Gigabyte UD3R does not support... regardless, my computer ran fine for 11 days with this ostensibly incompatible memory stick and the motherboard gave no indication that it wasn't compatible. The UD3R is a poor purchase decision considering the not so much more expensive yet superior ASUS P6T motherboard being available.
So if you learn anything from this post, take this with you:
1. Do not use Gigabyte mother boards, especially with unsupported memory
2. Shop at Micro Center
