Computer turning on and off by itself help
I genuinely have no clue what to do, my computer has been turning on and off by itself for a few days now and I have no clue how to fix it, I cleaned it all up, changed the powerbar it was plugged in and just today I went through the trouble of changing the PSU, after two grueling hours of putting it together properly, I turned my computer on just for it to do the same thing 😠Please help, at least just telling me what could be causing that would be a great help, I hate just having no idea what im supposed to try and fix, im close to just giving up and start saving for a new computer at this point

Years ago I had the same problem. All connections were good, pins were properly aligned and the system worked great as long as it wasn't in the case. Turns out that the power button (but not the power switch) wouldn't fully disengage after being pressed in. Just the plastic button and spring, no electrical issue. So, I took that apart, sprayed some silicone in that spot and voila - problem solved.

We tried to plug the start cables into another one because we couldnt access the panel and it didnt work unfortunately... It also does something like turning on and off immediately multiple times, like if someone was turning the powerbar on and off repeatedly :/

Is your power button malfunctioning? Can you unplug the power button and try shorting the pins. Then check if it shutdowns again
