So this is my first build and I recently received all my parts via mail and when I (carefully) assembled them the first time, only the PSU would seem to power on when I flipped the switch. I took the computer to a tech and he stated to me that the mobo was probably DOA. So I did the RMA (for ten bucks at newegg btw) and got a replacement.

So I reassemble everything back together and lone behold, the same issue!!! The PSU lights up and its fan spins and then I see the AudioBoost for the mobo flash and then nothing else initiates. Specifically the CPU and the graphics card's fans do not start and there is no boot.

Any help or suggestions would be greatly appreciated. My build's specs are:
-MSI z87-G45 gaming mobo
-MSI N760 2GD5/OC graphics card
-Rosewill RBR1000-M 1000W psu
-Corsair Vengeance 8GB 240pin DDR3 ram
-Intel i5-4670 Haswell cpu
-WD 1TB hard drive

I'm not really that experienced with computers and I wouldn't really know where to begin testing the parts w/out pressing the power button haha
 
I have the same motherboard as you. I got it for $139 a few weeks ago on Amazon. I have not hooked it up yet as I still need to order a new case and hard drive.

Are you certain that you have all of the power connectors plugged into the motherboard and also the CPU's heatsink fan?

I'm fairly sure that I have it connected correctly, my biggest suspicion is that the PSU is somehow to blame. It seems like an awesome mobo but I can't really tell yet. Might take it to Geek Squad to see what's up. Here's a quote from another tech I took it to, "Removed all components and tested just the motherboard. Computer will not power up, tested with our own parts. No power indicator lights come on. Bad motherboard." danny2000 have you ever bought anything from Newegg? I doubt they's send me two bad mobos
 
I've bought plenty of things from Newegg.com. I always compare rates with shipping, rebates (amazon will often have the same price as the rebate, without having to actually submit a rebate), etc, on Newegg.com, TigerDirect.com, and Amazon.com.

 
What I would do is unscrew the power supply from the case and remove. Ensure that you also unplug any connectors that are plugged into the motherboard from the power supply so that you can remove the powersupply from the case.
.
Unscrew the video card and remove
Unscrew the Hard drive and take out.
Unscrew the motherboard from the case.

Now set out a large piece of cardboard on a countertop or desk and place all of those items onto the cardboard. Move the computer case out of the way somewhere as we won't be using the computer case for this test.


Hook up all of the items on the cardboard (again, no computer case).

Now with the computer setup outside of the computer case, look on your motherboard at
JFPI and touch with a paperclip, connectors 6 and 8 which is for the POWER SW that should turn on the computer as that is the connection for the Power Switch from the front of the computer case. Look at the MSI manual (Page 1-26))to ensure that you select the correct one.

You can hook back up the M-Connector and remove the one that says Power SW from the M-Connector (page 2-11).

Then use a paperclip to touch the two pins where the Power SW was plugged into.

If it powers on, then you know it is a problem with your computer case and nothing else.

Hey so I took my set-up to Geek Squad and they told me that my most likely issue was a bad PSU. When they used a PSU measuring device, they literally showed me that the device showed no readings whatsoever. So right now I am in the RMA process for the PSU and I hope that is my issue and I can finally get it resolved. Thanks for the help so far, I'll let you guys know if it was a DOA PSU.
