Question PC wont boot after AIO and case fan install.

[CQuaid]

Hello. Last night I installed a new Aio cooler and replaced my case fans. Went to turn my pc back I had power to usb components but the system wouldn’t boot. Im not very experienced with pc hardware. My system was running hot figured i would replace the fans. Installation was fairly easy. Not sure what the problem is. Any help would be appreciated.

Make sure there's a fan connected to CPU_FAN connector. Usually those are fans for radiator.

Yes the AIO is pluged into CPU FAN
