I bought a ryzen 2600 to upgrade from ryzen 1300x, once I swapped the CPUs the system stopped working. I took out the motherboard to do the upgrading. I got 2 mobos that I tried with both cpus the original is a b350m gaming pro and the other mobo is a rog strix b450 f gaming mobo. I had to order the b450 f because I thought the other mobo was bad. I tried 3 psu with both mobos all failed work to turn both mobo on. The 450f logo lights turn on. And the USB drives work my keyboard turns on when I flip the power switch on the psu. I tried breadboarding but nothing turns on, except for the mobo logo light and my keyboard.
