My psu is On but when i press the power switch, everything turns on for half a second then makes a click sound then nothing tu

Solution
Power supply is going into protected mode for some reason. That click is the power supply itself throwing its protect for reasons of heat/short/current/voltage/ect. Good luck trying to figure out why. I would guess motherboard issue. The power supply itself could be bad as well.
