My system still won't turn on. I have 3 motherboards 2 are brand new 3 sets of ddr4 ram, 2 different power supplies, 2 different ryzem cpus, and 2 different gpus. I have tried everything besides getting a new cpu and a new case. There is absolutely no power it won't flash blink anything. I'm getting scared at this point cause I have everything to make 2 pcs that are about 2 grand a peace and nothing works. Any advice? Besides unplugging each cable one by one checking each ram stick one by one changing power cables changing cases. The only thing I have not tried is the cpu but I'd rather not have to buy a new cpu if it's possible.
