PC will not completely turn on?

[ArmenianMobster]

​I recently transferred cases along with a EVGA 650w psu and my PC booted up smoothly after I finished. The problem I am having now is when my PC is off for about 12 hours or so, only my heatsink/fan will start (Hyper evo 212)!?!? Not even my case fans will turn on and same with the LEDs. I have to turn off my psu and turn it back on for my PC to then boot properly. I dont know what the problem is and I'm hoping you can help me.

On the other, my PC runs smoothly after its on. No complications.

 

Spec:

i5 quad core

GTX 660

Z97-C ASUS motherboard

8 GB ram

 

Thank you!!

When you press the power button on, only the CPU fan spins, no other fan in the system and no video output correct?

Is it plugged directly into the wall, or through something like a power bar?

Make sure you didn't plug a cpu header into your gpu
