What does my beep codes say about my system?

Today I built my first-ever computer (it was exhausting)

Never done this before, Was too afraid

When I turn on the power button, I get the following beep code (you can hear them here)

I tried to consult my manual but there’s no beep code manual

can you help please?

thank you!

edit: the fans, the lights and everything works as expected (the cpu fan works and spins, so does the case fan)

edit 2: when we took out the ram, the noise still was there, but sounded in really low quality

also, no display. Not vga & not hdmi
