I don't post on boards much.  I'm relatively inexperienced, this is the second time I've assembled a computer.

Everything appears to be installed properly, but I cannot get any of it to power up.  Only evidence of current is the blue touch power button/OC genie will light up when depressed

My components:

Corsair 750W PSU
MSI Big Bang XPower Mainboard
i7 930 processor
XFX Radeon HD 5850 GPU
3x 2GB Corsair DDR3 Dominator RAM

Thanks very much for any assistance.

A common mistake people seem to make is installing the RAM into the /blue/ slots instead of the *black* ones on a 6 GB system.  Make sure your memory is installed in the *black* slots.  If you still have trouble, try just one memory module first and then adding more as you test...

Did you plug in PSU power, the 4/8 pin near CPU? All power plugs for VGA card?

See the manuals for MB & VGA card location of all power connectors.

I did initially do the black RAM slots, and I do currently only have one installed in the DIMM 1 slot.

I do have the PSU plugged into both the 24 pin slot on the mainboard as well as the 8 pin slot near the cpu.  I actually went to microcenter today looking for a peripheral to 8 pin slot in the off chance such a thing existed and i needed both slots filled to run the cpu (something other posts have reassured me is not a requirement). 

There isn't like an "on" switch I'm missing somewhere is there?

On the RAM, just to be clear, you have one module in the first black slot from the CPU, correct?  (Please see the memory configs in the manual.)

I have a Corsair VX550W power supply which has only one 8 pin CPU connector.  I connected it to one of the CPU power connectors, the lower number of the two, #2.  You do not need to plug in the secondary 8 pin CPU power.  The system only needs one, unless you're doing some heavy overclocking, which will require a power supply that gives you two dedicated 8 pin CPU power connectors.  The manual explicitly says *not* to use a PCI-E 8 pin connector for the 8 pin CPU.

There wasn't a special "on" switch that I had to switch.  Make sure you turn off the OC Genie.

My power supply is hooked appropriately at one 8 pin and the 24 pin slot on the motherboard.

I have one, 2 GB stick of DDR3 1600 Corsair RAM installed at the first black RAM slot (DIMM-1)

Right now all that I have connected is my mainboard with my processor, processor fan, and one stick of ram installed attached to my power supply.

Add the VGA, remove the power cord from the PSU, clear CMOS & reset.

So I

1. Unplugged the PSU from the wall. 
2. Attached the graphics card to the mainboard. 
3. Attached the PSU to the graphics card.
4. Held the "clear CMOS" button for ten seconds.
5. Plugged the PSU back into the wall.
6. Pressed the reset button on the motherboard.
6. Tried to turn the system on by placing the flat head of a screwdriver across the power-on switch.

Nothing happened.

Also, although the blue LED above the power switch on the motherboard lights up when pressed, the blue LED above the reset button does not.

Remove the MB from the case and re-test with it out of the case. Set it on a sheet of clean plain brown cardboard for testing. Do not put plastic anti-static bag under the MB as they are electrically conductive.

I think Henry meant "Do *not* plastic anti-static bag under the MB...".  Just use the cardboard.

I haven't personally seen the motherboard blue LED condition you're seeing, but I'm sure some tech has...  or knows what it means...

All of this has been done with it out of the metal case, on the cardboard box the mainboard came in.

Thanks for the continued help, guys.

Try reseating the CPU & checking the socket pins for slight bends. If possible, test board with another CPU or test CPU on another X58 board. One or both may need to be RMA'd.

I've reseated the cpu a number of times.  One thing I was wondering (if anyone else is using this case) is the processor supposed to fit very snugly in the metal cage?  I'm certain that its aligned correctly, but I was a little surprised by the amount of tension I had to exert to close the metal cage over the processor. 

I have no second psu or compatible computer to test this with.  Can you guys guide me through the best way of testing the individual components? 

PSU, motherboard, processor. 

Also, what's the bare minimum I have to hook together to make the processor fan run... Just motherboard, processor, RAM, PSU?

After buying this piecemeal over a period of time (to take advantage of good bargains) I'm not sure that all of my components are returnable.  So frustrating.

Okay, just to double-check:

Have I understood this correctly?

-> When you try to power-up the system (by pressing the power-on button of the board
power_button.jpg
, the power-on button of your case or by shorting the two power-on pins of the respective pin header), when you try to power up the system like that, the result is that absolutely nothing happens, right? No fans start to spin (not even the PSU fan) and there are no additional LEDs lighting up on the board.  Is that correct?

If that this is the case, then you should only concentrate on the following two explanations:

1) The PSU is damaged or not hooked properly (test another PSU).
2) The motherboard is seriously damaged (power circuits).

Since it is hard to test theory #2, the next thing your should do is to check theory #1.

I have no second psu

Well, then need to get your hands on one.  What computer are you using to be able to write here in the forum? 

Call everyone you know. There is got to be someone who is able and willing to supply you with a PSU for testing purposes and willing to help you with this.

If I press the power button, the LED above the power button lights up, that's it.  And it doesn't stay on either, although I don't know if that's its intention.  It lights up when I press it, and turns off when I stop.  The fan attached to the graphics card and the processor fan do nothing.

I can dismantle this computer, but God help me if I can't put it back together again.

I just moved to start residency, I know no one in this place.

Well, either you find another PSU for testing or ask in a computer shop for assistance.  Otherwise you will not really get anywhere from here.  You could also simply RMA the PSU or buy another one.  If that does not change anything, I believe it is RMA time for the board.

Sigh.  I'll go buy a new psu tomorrow and attempt the switch.  If that doesn't work, I'll try the motherboard.  If neither of those works, I'll be back on here trying to figure out where I'm going wrong.

Otherwise, can you recommend any chains that might be willing to look over my hardware?

Thanks everyone for the help.
