Only the CPU and Chassis fans will run on a cold boot on a new build machine

I just changed out my motherboard and case from a Shuttle Z77 system to a mid-tower ATX case, and I am having an interesting glitch. Here are the parts I used:
Motherboard: ASROCK H77 Pro4/MVP ATX board, specs here.
Intel i7 3770K
32gb (8gb X 4) of Corsair's Vengeance series specs here. (I know I went overboard on the RAM, but it was on sale!!!)
MSI nVidia 660ti GPU with 2gb of RAM.
700W Cougar modular PSU, specs here.
Cougar Pioneer mid tower case, specs here.
Samsung 820 Series 256GB SSD as boot drive and 2tb X 2 Hitachi Deskstar HDD for storage.
Windows 8.1 Pro

Sometimes from a cold boot the machine will fire up right away, but sometimes when I push the power button, only the CPU fan and one of the chassis fans will run, but they run very slowly. This appears mainly to happen when the computer is shut off overnight. I then unplug the machine from the wall and wait about 10 minutes. Plug it back in, and it will fire right up 90% of the time. Sometimes I have to repeat this process a couple of times.

This is what I have done to trouble shoot the problem.
1. Used the new power supply on the old computer, and the PC posted.
2. Used the old PC's PSU on the new build and it posted.
3. removed the motherboard from the case an tried starting it adding more hardware after each successful boot. I ended up having everything attached with the machine working fine.
4. Repeated step 3 with the old PSU with the same result.



I am at a loss. if anyone has any ideas why this is happening, they would be greatly appreciated.

Thank you in advance....

The problem has been solved. The outlet that I had the machine plugged into had a condition called "hot ground". Power was trickling into the PSU through the ground wire, and over time it was tripping the protection circuit on the PSU.
