Question Pc randomly turned off, and won’t turn back on

[payday2isfunlol]

3 weeks ago, while I was playing a game, my pc randomly turned off. I tried turning it back on, but it wouldnt turn on. I reseated the ram, tried booting without the gpu, replaced the cmos, replaced the cpu with a older one (upgraded from that), and replaced my power supply. Those did not fix it. What do you think needs replacing?
