Computer won't boot- Mobo?

Modifying an existing build. Please Help!

I bought a new Power Supply and Motherboard. (Just was time to upgrade.) However, my computer won't "boot", even though I know everything is in the right place and should be comparable. I have done a number of builds, and never had this problem.

When I press the power button, the computer comes on, all the lights and fans come on, however my monitor never receives any signal. Nor does any USB device I have plugged into the mobo.
Upon closer inspection, the CPU_LED light is on- the cpu should be fine, I just moved it to a new mobo is all.

My build:

Mobo: ASUS: Z97-A
Processor: Intel i7-4770k
Power Supply: EVGA 1000g 80+
Graphics Card: Radon 280x with an XFX black "double d" cooler.
RAM: 8gb Ballistic ram (x2)= 16gb
Processor Cooling: Corsair h100i
1 SSD
2HDD

Please help, I am desperate, my job is audio editing, I NEED my computer ASAP.

Thanks! And sorry for bad English. :)

Does the motherboard have its own GPU? sometimes it's set to display from the onboard and then you'd configure the BIOS to receive a signal from both or the dedicated and then reboot with the DVI/VGA or HDMI in the dedicated graphics card

mrsweet1991: It does have a dedicated GPU, which is why I then tried pluggin my monitor into that instead of my other graphics card, no luck so far, I will look into what you said. Thanks!

UPDATE: I found out how to "reset" the board by unplugging the power supply and removing the on board battery. Now the MEM_OK light is solid on, and the CPU light is no longer on. The ram should be fine.....

So all that goes through fine but you're still not getting anything from either the onboard input or your graphics card? Any BIOS sounds?

Nothing at all: No bios sounds to speak of, but to be honest my fans out quite loud. Thank you for your time.

Not a problem, if you leave your system on for around one minute when you press the power button does it instantly shut off like literally in under a second? or do you have to hold it down for around 2 seconds before it shuts off... the idea behind this is because we can't see what's on the screen we can guess if the system is stuck at the POST screen, or if it delays to shut off it may very well be booting but there's no video signal.

Good point. Also if he has speakers plugged in he could possibly hear windows startup sound. Unfortunately I do not believe that is the issue.

No windows start up sound- plugged in speakers.

It takes quite a few seconds from the time I press (and hold) the power button until it shuts down. (Between 4-7 seconds)

Also: had the thought that since the memok light was on, might as well check the ram. Plugged the cards into another computer, worked just fine.

Definitely worth a shot, at least you've narrowed it down a little :)

New update: I had a slightly older (but considerably smaller) mobo that I plugged my essentials into a la workbench style and I got an ideal boot. So that, at least in my mind, means the problem resides in my new ASUS Z97-A mobo.

Dram light constantly on, no solution, not starting up. Could I simply be dealing with a faulty board?

Could be, what RAM are you using? I personally have never experienced incompatible RAM but it could well be it's not compatible. Also how many sticks of RAM do you have and how many slots are available on the motherboard.. what I'm getting at with this is if you have 4 slots for RAM but only two sticks sometimes they have to be in specific slots

I have two cards of "crucial ballistix sport 8gb"

They are currently plugged into slots 2&4 per the user guide, however during this I have tried every feasible combination of slots and ram.

From my knowledge you've tried a good few different things and it could very well be leading to a MOBO issue.. was it new or?

Brand new. Bought it from Micro Center about 48 hours ago.

Hmmm would seem unlikely wouldn't it, maybe hold it for other peoples inputs and then maybe think about ordering a replacement if all else fails?

Due to the impending doom that is this assignment's deadline, I am going to plug up my old mobo that, although isn't nearly as good, allows my computer to run what I need it to do.

I appreciate all of your guys help, I have 28 days left to make a decision on this mobo that started the thread. If anyone comes up with anything, I would love to hear it before replacement becomes my only option.

Thank you so much for your time/input!

To anyone still following this thread-

My curiosity got the best of me. I have a buddy who works at Corsair as a system analysts. They have a system tester that they can plug a whole bunch things into various components and it gives then unique error codes to tell them exactly what the problem is. It wasn't any component, but actually where the main power supply lead connects to the board. (I believe it is 24 pin.) One of those pins on the board itself was not properly soldered in, so the board was not properly receiving electricity. Since he professionally works with this stuff, I asked him to fix it, he did it in 10 min. I was amazed.


Thank you everyone for trying to help me on this peculiar problem!

Wow, it's great that you have your friend otherwise that may have been seriously hard to diagnose.. I mean saying the motherboard is faulty is one thing but getting it down to a pin on the motherboard And fixing it is impressive :)
