I am building with a STRIX X370-F motherboard, Ryzen 7 1800X CPU, liquid cooler, and 2 x 16 GB DDDR4 RAM. I put the MB into the case, fitted the CPU and cooler, plugged the DRAMs into slots A2, B2 as per the installion manual, and plugged in all the cables.
When I powered up all the fans came on, the MB standby light comes on, all the fancy light show LEDs come on - and that is it. No POST beeps, and the four debug lights do not even flash.
This is actually the second motherboard I have tried, as I had the original replaced on RMA. So any suggestions? Could it be a faulty CPU?
