Asus P6T Deluxe v2 wont power up

Hey,
I just bought my new Asus p6t Deluxe v2, together with an intel i7 920, 4gb ddr 3 (duel channel) ram.
I've got an 850 watt power supply and an Geforce 9600GT and 1 terabyte harddrive sata 2 in it.
When i try to boot my system up, all coolers get like a startup shot, like its booting up but they all fall down in less than a second but the power still runs through the motherboard since the lights still burn, and i need to hold the power butten 5 seconds to retry it.
When i tryed it a couple of times more there came smoke out of the motherboard... not sure what part but...
Anways, what did i do wrong ? or is this motherboard just defect ?
Im sure i did connect everything right, not sure about the 8 pin power connector in the top of my motherboard though.
I just used a 8 pin from my power supply (not the ones for pci-e ofcourse)
I wish to hear from you forum members because im really really desperate right now

Greeets!

Thanks for the help!
I finaly got a post!
Only now i can't enter the bios, and i need to update it to see my intel i7 920 d0 stepping...

I have the same problem, got it in the mail today with i7920 from newegg, powers on for 1 second or so, then shuts down

This sounds rather familiar: I went through two Asus P5Q boards (Pro and Turbo) with similar problems. The P5Q pro board gave one flicker of light to the 'power on - standby' led and then remained quite dead: No lights no nothing. Returned that motherboard and swapped it out for a P5Q Turbo (no Pro's left in stock). The P5Q Turbo fared a little better: Fans on, power up and: No Video, No Keyboard, No Mouse, No Beeps! Returned that board and swapped it for a higher end P5E Deluxe. P5E Deluxe started up with no problems.

Before I returned the bad P5Q boards, I had tested the power supply (OCZ Gamer Extreme 750W), my trusty olde honeywell keyboard, logitech mouse, ATI Video (HD2900XT), the hard drives, the DVD burner and my 4 sticks of Crucial Ballistix Tracer 1066 RAM. All components tested out fine; although it looks like the P5Q Turbo burned 3 out of my 4 sticks of RAM although I can't be completely sure!

Long story short: I'm assuming that your keyboard responds (you can get the num lock light to go on and off) and your mouse (hopefully optical) actually glows to show it's receiving power from the USB connection.

-Have you tried resetting the BIOS using the CLR jumper? I usually play it conservative with a BIOS reset and (yes unplug mains power) remove the button cell battery then set the jumper to clear the BIOS of its current configuration. I usually let it stew for a couple of minutes; albeit ASUS recommends 10 to 15 seconds. My P5K board that recently died after 2 years had that lovely no video problem and multiple BIOS resets brought it back.

-Have you checked for bad RAM (more than just the sticks). A bad stick can cause weird things to happen even during startup and post. Also note that every component has some amount of ram in it; I once had a DVD burner cause all sorts of havoc that had no pattern and eventually the mobo wouldn't post; the problem was the DVD drive's onboard cache... It's RAM was 'pooched' and given that everything in the RAM world gets pooled, it caused the whole system to become unstable and then fail to post.

-One of the age old recent problems is the power hungry video card: Depending on your configuration, OCZ recommends 800w or better power supplies for high end video cards that use the 6 plus 6/8 pin above board power connectors. If the Video card in these cases doesn't get enough juice, the system just plain won't start and definitely won't post.

-Talking about power supplies: Have you had it tested to make sure you are getting stable power from all rails?

-That there 8pin used to be a 4pin ATX power connector next to the processor: If you've got a board that has the 8pin ATX rather than the older style 4pin ATX, you need to connect a full 8 pin connector or the board won't start / post. Not enough 'go-go juice' to get the board moving. If your power supply does not have the proper 8 pin connector for the ATX power, it is more than likely that the PSU is either an older model or an entry level model that does not have what it takes to power the mobo (Some PSU's like OCZ use a 4+4 connector).

-If you don't get any keyboard / mouse response and your getting no video and no beeps: I would be siding with the DOA mobo problem on this one.

PS: The techs at my local computer store confirmed that both boards were defective!

PPS: Anytime smoke comes out of a mobo; something has definitely blown on the board! Not a good sign and probably now dead!

i had a similar problem, with similar components (i think): when i started the computer it just came to showing the first screen with the Asus Expressgate-options . then the computer would restart all by itself and come to the same screen, restart again and so on, and so on.
the solution to my problem was to enter BIOS by pressing DEL before the computer restarted by itself. then simply turn OFF the ASUS EXPRESSGATE option, save and exit. after that my computer booted without any restarts or other problems.
not sure if it will solve your problem, but it might be worth a try.
peace out and good luck.

i had the same problem. I stripped the MoBo of everything besides ram, video card, CPU and fans.

I reflashed the bios and booted up.....

didnt work

then i realized that I was trying to boot in the A2 slot (A2,B2,C2 are the black ram slots) for my RAM

once I switched it to B2 and reflashed the bios again (unplugged and battery pull for 1 minute), it booted up fine!

figured I would pass that on since its a reoccurring issue

I'm having the same problem as Billiam. Powers on for about 1sec, then powers back off. Weird thing is that even after I remove my finger from the power button, it will continue to try and power on. But it will just power on for about 1/2 a sec, then back off, on, then off, on then off.

Tried removing ALL components except motherboard and PSU.
(even took out memory and cpu)

It won't even spin up the fans.

Thought it might be a case grounding issue, so I took the mobo and PSU out of the case, and tried booting it on a wooden table.

Still no go.

I then RMA'd my PSU, AND my Mobo.

STILL NO GO!

I'm going crazy over here. All of my warranties are about to expire and if I don't figure this out soon, i'm SOL.

Oh, also, i'm using a P6T Deluxe V1, not V2.
