PC Shuts Off Immediately

Hello all, looking for some help with my pc, I built it a few months ago and suddenly it has started having issues, i haven't cleaned it or messed with anything on the inside

It shuts off as soon as I start it, I've tried resetting cmos battery, removed it from ups and plugged directly in the wall, reseating the ram or just running with 1 stick.

It's been about 6 months of it running perfectly and suddenly it just started doing it
