Computer turning of and then back on continuously!

Hello!

I'm currently building a computer and already having issues. Everything is put together properly. When I turned it on the first time, it said "CPU or memory changed!!!..." and after a few seconds of that screen, something made an electrical snap and turned off. I tried powering it on again and it didn't turn on. I tried another PSU and it turned on, but I get no display! It will turn on for a few seconds and then turn off, turn on again, turn off again, and so on. I get no display either.

What's going on???
