So ive been through 2 motherboards and 2 cpus. On both of the configurations the rgb cpu fan and graphics cards would light up. Same as the ram. Mobo is x470 pro carbon. Cpu is ryzen 3700x and ram is trident z 3000 mhz. All parts are brand new. Has to be trchnical issue bc ive gone through the same mobo both of wich were new 2 times and same w cpu. I need help rip

Ya seen it, but didnt work. X470 carbon pro looks different but also nothing lights up when i put in the flash drive and wait 5 sec after pressing the button. Im just going to return and get an x570 so that at least it will boot w out having to have a usb flash back
