Before you discard the CPU if your BIOS has PBO option turn it off, with latest BIOS on my B350 motherboard version 5406 PBO is on by default and apart from causing high temperature it would lead to this kind of crashes and reboots with my Ryzen7. Turning off PBO fixed it and now I am running a Ryzen9 with the same board and all works fine with PBO off.
