New computer constant restart

[SynCroNiz3]

So I just got a whole new intel core i7 build, and I was excited to put it all together, low and behold, once it's all together I start it up and it just goes into a loop of restarts. Now I've tried multiple things, taking the system out of the case, running just one stick of ram, trying different ram modules, rewiring it, and etc. But no matter what it just ends up restarting. At some points I can actually make it to the bios, other times not. Farthest point I got was, I actually started installing vista, and just when I thought I might be in the clear, it restarts, about a quarter way into the format. I'm starting to wonder if it's just the motherboard. Any help would be appreciated, thanks.

System Specs:

Intel Core i7 920
Gigabyte GA-EX58-UD5
Ocz Gold 3X2gb ddr3-1600
XFX 4870X2
Seagate 500gb 32mb cache hd
Corsair TX750 watt psu

Couple of things if you haven't tried them already....

Reseat your heatsink.

You didn't mention resetting your c-mos so try that if you haven't already.

If you haven't already gone through this list... 10 Step "No Post" BIOS Recovery Guide try the steps in there, but it sounds like you have probably gone through all of them already.

Other than that... the only way to really know for sure what's going on is to start swapping components, and that's never easy to do with a new platform.

One thing I'd also swap out would be the power bar you are using. Or at least plug in the computer directly into the wall. I've seen cheap power bars cause this type of problem. Took me about 2 or 3 days of swapping parts, returning parts etc until I figured it out.

I would definitly reset cmos first thing.

Also , is the motherboards bios up to date ?

If you can, check the voltage on your power supply. I have the same PSU, and I had to RMA mine due to a faulty 3.3v rail that was causing my computer to shut down under load.

Appreciate the help guys. After trying everything I could, and doing all the suggestions possible, I just cannot get this thing stable..at all. No matter what reboots 2-3 secs into starting it. Last thing I'm going to do is take it to my local computer shop to see if ram is faulty, and test the motherboard. If all else fails I'm going to rma the motherboard.
