Computer won't boot, could it be the motherboard?

Around Christmas of last year I built a PC that I've been using for gaming, after taking a few hours to assemble it all it worked flawlessly and I never had any problems with it. A few days ago I was playing a game and my computer just up and shut off without warning, afterwards it wouldn't turn back on. I tried to barebone it and got nothing, I tried taking it apart and putting it together again and got nothing, I tried booting it without RAM, and nothing, I tried booting it without the video card and got nothing, I also tried clearing the CMOS to no avail. I assumed that my PSU died so I ordered a new one, replace it and connected everything again and still, nothing. If I press the power button after letting it sit for a while, the power LED will flash on the inside of my case and the fan will turn for a less than a second and then I get the same nothingness as always. I'm completely out of ideas on what to try so the only thing I can think of that'd be causing this is a dead mobo, however I'd like to get some other opinions before shelling out a few hundred dollars on a new one. I'll post my specs as well if that'll help any. Thanks.

Case: Cooler Master HAF 912
Motherboard: ASRock Z77 Extreme4
Video Card: Sapphire Radeon HD 7950
RAM: 2x Kingston HyperX 4gb
CPU: Intel i5 3570k
PSU (Old/Original): Antec NeoECO 620w
PSU (New/Replacement): Rosewill Green Series 630w
 
Solution
Unless you either have had 2 broken PSUs in a row or a cable has failed it could only be a mobo problem yes. try looking at all the pins in connectors and have a look at the cables on the psu make sure nothing has been cut or bent. Then it is most likely the mobo.

Check the CPU core power cable.

I've looked over everything multiple times and didn't see anything that looked broken or messed up so it doesn't seem like anything could be wrong there.



I've checked all of the cables and none of them had anything wrong and they were all in properly so I don't think it's that either.

Unfortunately there's no shops near me so it's looking like I'll have to buy a new one.

Thanks for the quick replies everyone.
