Faint "beeps" coming from PC every few seconds

[Sassanid]

So around a year ago I built a new gaming PC and everything works fine but my PC always makes these faint beeping sounds and I have no idea where it's coming from. I thought before I start taking things apart and diagnosing the issue, maybe someone here has ran in to this issue before and knows what it might be and I could save some time and address that area directly.

I took a small video where you can hear 2 beeps, seconds from each other. It might be hard to hear from the video but when you're sitting at the computer and there's no other noise, they're very noticeable. The 1st beep is right after the sound of a mouse click at the start of the video, and the second beep is near the end of the clip. You can imagine this happening all the time all day.

I'm wondering if it could be a fan or something because the beeps are totally random, sometimes it happens 20 times a minute, sometimes a minute goes by with maybe just one beep, and it's not a digital beep like the boot up mobo beep, it sounds like a faint mechanical whine or beep coming from hardware. I've dusted and cleaned my whole case and fans and the problem has persisted. I appreciate any tips.

Oh and hardware:

MSI MPG Z490 GAMING EDGE WIFI ATX Gaming Motherboard
Zotax 3080Ti
i7 10700K
M.2 Barracuda SSD
G.Skill Trident Z RGB Series 32GB

Are you sure it's coming from your PC?
Do you have a UPS in the room?

What is the linked picture? Like IDK what that is even showing us.

Where is this video at?

All I hear in the video, are clicks sadly. If ya want to record the beeps, quit using the mouse/Keyboard?

If only happens when doing things, could be confusing coil whine with a beep?

Are you monitoring temperatures?

Some mobos give a warning beep if things get too hot.

[Bad 💀 Motha]

The beeps could be from you unknowing triggering hotkeys that enable certain WinOS functions such as StickyKeys or MouseKeys for example.


You said only when doing things? Like what, like only when running a game or benchmark? That could easily be coil-whine coming from PSU or GPU that changes to a louder audible pitch when the PSU load is high, or from the GPU when the FPS is really high.

Sorry the video is facing down towards the ground from the edge of my table, and that's just my laptop leaning against the PC that's turned off. I'm going to take another video closer up and turn up the audio.

Just to clarify, the beeps...

- are not mobo/PC related beeps, those are loud and audible when something goes wrong, or when booting up, these are faint but still noticeable

- they are totally random, it's happening now when I'm typing every 10 or 20 seconds. Sometimes when just browsing with mouse. Sometimes when I'm not touching anything

- yes temps are fine, idle temps for CPU and GPU are in the 30s, and max gaming temps are in the 60s and 70s

Will be back with a longer video without any mouse/kb clicks

Sounds like harmonic beat

Maybe 2 hard drives spinning at similar speed / frequency, or fans or something

Biggest question is.... why do I now hear it in my room after the video has finished playing ?...

I am telling ya, a mechanics stethoscope is key for physical PC hardware diagnostics. They are also inexpensive and can pinpoint issues where within...

I just bought one from Amazon for around $10 and will try to isolate exactly where the beeps are coming from, thanks for the tip :)

I rly don't think it's a HD issue since I'm only running a 1tb M.2 drive right now, no spinning parts or anything

open windows mixer and mute everything to rule that out
