PC not powering on

Parts list:

Ryzen 5 1400, Patriot Viper 16gb, MSi B350m + Asus A320m, EVGA GTX 1050ti SC, Corsair 100R, EVGA 430W + Corsair 450W


PC worked for a couple weeks, but now it won't power on.

Attempts to fix problem:

I have tried replacing the motherboard and power supply. I have tried breadboarding, as well as resetting the CMOS, but nothing's working. Does this mean it's my CPU that's broken?



Should I RMA it?

Let me know if any confirmation is needed
