My PC just shut down when I was in the shower and wouldn't turn back on. I had this PC for 2 years at that point and this happened in October 2019. At first, I thought the motherboard was broken but it was the PSU (no power coming from it), so I replaced the PSU. The motherboard lights up but when I try to turn it on the fans spin then stop immediately. I tried clearing CMOS, booting outside case, booting with no GPU, booting with no drives, and just one stick of RAM in DIMM_A2. Same problem. I then bought a new motherboard and went through the same process. Same problem. I did this with new RAM, a new CPU but nothing works. I keep getting the same problem. I've tried reseating multiple times but now I honestly have no clue what's wrong with my PC.
