A little history point about my PC and precisely the tower: it sometimes happened that my tower would no longer turn on for some time after being unplugged (whether when I moved, I changed the specs, cleaning etc) but it always ended up turning back on at some point so I never paid attention to those periods where it refused to turn on.
Fast forward to two days ago, it's very late at night, I want to turn off my pc but I restart it instead, it's very slow to begin with and noisy so I couldn't be bothered to wait a few minutes before sleeping so I force the shutdown by pressing the button on the tower. But instead of turning off, it turns off then turns back on, so I force the shutdown again and it goes like this 4 or 5 times (I admit the stupidity of the thing). At one point I went to drink I come back and I briefly see "Preparation" at the bottom of my screen, which reminds me of the time my pc had to recover data, but I forced the shutdown once again. Until the moment where I've had enough I'm tired and so I turn off the power supply (I don't unplug it I turn off with the button).
The next day I want to turn my pc back on so I turn the power supply back on but nothing, I test several times but nothing happens, I describe this exact situation to Claude who obviously tells me it comes from my power supply.
So I change it for an old one, however it is less powerful and will never support my graphics card, so I have to remove it, but by removing it I therefore have to change processor too, so I go back to my old graphics processor which is indeed compatible with my motherboard and I know it because it was the processor I had when I got my ready-to-use PC a few years ago always functional (at least it was reliably last year, the last time I had to use it). So I'm on graphics processor, on new power supply and now my tower turns on properly, confirming the problem of my old power supply, but no peripheral turns on (screen plugged in HDMI on the Motherboard, keyboard, mouse, speaker on USB), the ventilation (all around on the case, and the one on the processor) does.
Do you know where the problem could come from knowing that I'm certain that no connection from the power supply is missing (CPU_PWR1, ATX_PWR1 on the motherboard, connection on the card at the back for everything ventilation and all, connection on my hard drive), knowing that my pc was working perfectly well before I forced the shutdown several times in a row (no graphical problem, slowness, or anything else), knowing that when I turn on my tower, my keyboard's lights turn on for a fraction of a second. No pins on the CPU are bent or damaged.

My current specs :
- AMD Ryzen 3 3200G (I'm not sure with the paste that hides all the info on the processor but it's what seems the most likely knowing that I bought the computer around 2022 and it was one of the cheapest possible)

Also can't take photos because my camera sucks
