I have decent experience building pcs but im stumped. My pc specs are: Ryzen 9 3900x, Msi X470 Gaming plus, 16gb G skill Trident z 3200mhz ram, Gtx 1080ti, 1 Tb m.2 western digital ssd, 500gb patriot burst ssd, 1200w gold modular rosewill photon power supply. The bios is the very latest version (as of 6/12/20) and the pc works great when i swap the cpu to the ryzen 3 1300x. But when i put the 3900x in, the warning light goes red on "dram" and doesnt boot. Aka i dont get to see the bios. I hope its not a dead cpu, but it looks likely, any ideas?
