Why does the speaker beep non-stop about 30 seconds after logging into windows 10?

Question

motherboards

UPD DECIDED BY REMOVING AND NOT GOING TO AIDA64!
What could be the problem? I bought a new mother, it has the very first BIOS (January 2021), while there is no endless squeak in the BIOS even after 5-10 minutes of idle time in the BIOS.
Initially, windows 10 did not want to start at all, so I turned on csm and turned off security boot.
After that, windows 10 booted up, but the speaker began to beep continuously after about 30 seconds of operation.
Could there be a problem with an incorrectly assembled PC, or is the problem in the motherboard?
The speaker got it from another motherboard.
Motherboard gigabyte b560m ds3h. Bios AMI.
I read that this is either a problem with the PSU or overheating, but what kind of overheating can there be if the computer was idle in the BIOS for 5-10 minutes, and then overheated sharply. At the same time, the cooler dramatically changes the speed on the processor.

Answer 1

Has the video card been changed recently?
Maybe the power supply is not enough.
Once upon a time, programs made viruses squeak.
Remove everything from startup, reboot and see. Beep or not

Answer 2

Check your bios for fan speed and temperature control.

Answer 3

If the motherboard speaker emits one continuous beep from the moment the system is turned on until the moment it is turned off, and everything else works fine, I suspect that you either have the speaker connected to the wrong pins (check the manual well) or something is shorting the speaker on the motherboard .
