So I installed a fan controller today and the computer was working while installing it as I was turning it on and off and the BIOS would always boot up.

After I got all my fans hooked up I turned the computer off and put the side panels back on. Now when I pressed the power button the computer turns on for 3 secs, then shuts off then turns on and boots like it would but I have a no display error. Also none of the USB ports work on the back or front panels. I tried switching the DVI cord from the graphics card to the integerated as I have an i5-3570k and a z77 motherboard.

As this point I'm thinking it's the motherboard as I checked to see if everything was hooked up correctly and was securely in place.

Also, the motherboards VRM's are warm to the touch I'm just confused as to why I get a no display error when I try dedicated or integrated graphics..
