My Newly built computer will not turn on. It lights up for half a second then it turns off. I've read online and it says that it might either be the motherboard or the psu. The fans and the hd audio card lights up and turn off. If it turns on doesn't that mean that the psu is working? I don't know whats happening this is my first time building a new computer.
My Components:
MSI Z87-G45
Intel i5 4670k
Corsair Vegance 4gb ram
TR2 700w
ASUS GTX660
NZXT SWITCH 810

 
My guess would be the motherboard, it's shutting down after receiving power, likely a short, or it could be a safety mechanism finding something wrong. Contact MSI to figure out exactly what it is, and if it is the motherboard RMA it. They should send you one immediately and give you time to send yours back, usually it's a two week deadline before they charge your credit card.
