[Need help !! Power won’t start ...]

Hello all ,

I have a Thermaltake p90, I wired up a Gigabyte 1151, Deepcool AIO and other bits like ram, hdd, PNY graphics card with an EVGa 750w PSU.

i tried the paper clip test and my PSU works.

when I switch the power on the motherboard lights up with a blue LED light on the p90 chassis by the power supply, however when I press the button the chassis nothing happens, the fans don’t spin on the deepcool and the CPU I don’t think is coming on.

i have no idea what the problem is!
