Ps4 emits noise?

I've had the problem for a few weeks that my Ps4 beeps about 20 times in a minute even though I don't do anything to it or the controller, and during this 20 beeps it also makes a noise when trying to pull a CD into the drive resembles (although of course I don't do the same thing).

This noise also occurs when the Ps4 is switched off. I have woken up several times during the night by the beep, but the second noise does not appear.

When I disconnect the Ps4 from the power, of course there's no noise.

I look forward to any helpful answer

Best wishes
