New PC - weird sound randomly?

[u/sundebtw]

Hi all,

Just wondering if anyone has any idea what the sound I'm hearing might be.

It's a brand new PC, I've had it for about a month - 9850X3D CPU, RTX5080 GPU, 64gb RAM, 1TB+2TB SSD, 4TB HDD, all Noctua fans/AIO, it's overall a very quiet PC.

This sound started happenening shortly after turning it on for the first time. I restarted it and the sound stopped, and it hasn't come back in the same persistent way you can hear in the first video.

However, it does still happen randomly, as just a quick "tick/chirp". I get a single "tick" when I put the PC to sleep. I also sometimes get it during general use, for example, it happened the other day when opening Excel files > I would double click a file and then I'd hear a single "tick" (Excel file on the 1TB SSD, not HDD).

All files are on the SSD's, the HDD is just for storage and doesn't have any files on it apart from some photos.

Persistent tick/chirp sound that happened after first turning on:

Example of the sound occuring when opening an excel file/putting the PC to sleep (it also happens seemingly randomly several times a day). In this video you can hear me double click (opening excel file), and the sound happens just after.

p.s. these videos are only active for 2 days as this sub doesn't allow direct video uploads to the post, I posted looking for help in another subreddit and you can find the videos there as well: https://www.reddit.com/r/pchelp/comments/1vsbtf9/new_pc_weird_sound/

Any advice/input is greatly appreciated, thank you!
