Turned off PC with PSU switch now PC won't turn on

[4warhawk]

I brought my PC to my grandmas house and had to leave in a hurry. So I turned off my PC by flipping the PSU switch. I packed up my computer and when I unpacked nothing was damaged that I could see. I hooked everything back up and pressed the power button and nothing happened. I know I'm getting power because I plugged in my astro mixamp and it lights up. I built it three weeks ago and never had any power problems posted on the first boot up. But now nothing. Specs are:
Intel i5 4690k
Asrock z97 anniversary
Evga supernova g2 750w
8gb of gskill 1600 MHz ram
Stock CPU fan

Also never had any heat issues hottest it got was 79 degres on the CPU. I've read a lot of forum posts and I didn't find a solution. Any help is appreciated. Thanks in advance.

Have you opened up the case and made certain nothing came loose/unplugged during transit from Grandma's to home.
Try that first.
