No boot, black display, CPU Debug Light

My PC crashed in the middle of a zoom meeting and saw that the cpu debug light was on, tried reseating the CPU, CPU power connector, reseated the ram, tried using ram from a known good PC, nothing worked. I eventually RMA'ed the CPU and got the replacement today, installed the new CPU and same thing, no boot, screens stay off, and the CPU debug light comes on. I had just upgraded the cpu a few months ago and did update the bios so the only other thing I can think of is the CPU socket is dead? It sounds like I need to replace the mobo. But I wanted to get some opinions from others, thanks
