Ps4 flashes red beeps 3 times and goes out?

Have screwed my playsie and just the metal covers settled to a bit of dust to suck (especially the fan and no I did not let him turn quickly), I was careful and have wiped Komolett dry. I have no parts removed or otherwise

I assembled them normally and then connected. And she was completely quiet. But when I open a game, it flashes red and beeps three times and goes off without a message

What can this be and what can I do?

Maybe forgetting to plug in a cable on the board again?

Have not touched the board just over it said
