I have an AORUS PRO WiFi, i7-9700K, a Corsair RM750x, and two sticks of Corsair Vengence LED. When I first built the PC, I put everything together and tried to boot it. When I turned on the PSU, there was a brief flash of the lights on the motherboard, and when I pressed the power button on the front panel the PSU would click twice. The RAM sticks would light up, but the motherboard lights would not, no fans would spin, no status LED's would light. So I sadly disassembled the entire build and started fresh. I installed the CPU and RAM, and then hooked up the PSU to see if it would do anything but the result was the same. I've tried the fan trick with the PSU and the fan spins up, and I've tried all combinations of RAM sticks in all of the available slots, but some combinations cause the PSU to click a few times, sometimes in quick succession. I'm just at a loss, is there anything else I can try or do I just need to order new RAM or take the MoBo to a repair shop to be tested?
Thank you for the help
