Here are our recommendations for this issue:
- Test the system out of the chassis.
- Test a different power supply if possible or power outlet to narrow the issue.
- Try to identify where the sound is coming from in the board.
the sound comes from the motherboard speaker. With motherboard out of the chassis the problem remains.
I have record the sound and upload it. You can listen here:
after 20-30 minutes the sound vanishes. What it can be?. Until today the motherboard works right.
I have another 400w power-supply for testing but I'm not sure if I can plug it to this mini-itx motherboard
Please, If you think the motherboard is damaged tell me something to ask dealer for a replacement.
thanks for your help!!

We would like to inform that there is no specific reason for that sound coming from the board speaker. You can proceed to check your warranty options to replace the board.
ok, thanks for your answer.
I will go for a replacement.
I had the same sound om my D2500CC, removed the jumper above the speaker and the sound vanished. I think it has something to do with the power supply, PicoPSU.
Thanks for the information Backard,
Please let me know if you are able to test another power supply?
Also please test the board out of the chassis with minimum configuration to discard any grounding issue.
Please make sure you are using the latest BIOS version and drivers.
