strange sound My pc make's a strange buzzing sound

[MarvinKlinge]

My pc makes a strange buzzing sound, and I don't know where it's coming from or what's causing it.

And the strange part is that it only happens when the pc is under load!

If you have any idea what's causing this, please tell me.

 

I have I little video from my phone so you can hear the buzzing sound.

(And I'm sorry from the background noise)

coil whine, doesn't hurt hardware but can hurt your sanity

As Jurrunio said it's coil whine. could be coming from the GPU VRM, CPU VRM or even the PSU, sadly you can't really get rid of it. Try undervolting to reduce it.

Thank you I will try to reduce the voltage on some components and hopefully, I can find the source.

Sounds like GPU, but hard to say. Try to run a CPU load on it's own and then a GPU load. If it only happens during one of the tests you have your answer.

 

What are the PC specs?

What's the motherboard? I'd guess it's the GPU, try reducing the power limit and voltage and see does it get quieter, usually coil whine is proportional to the voltage and current load.

Its a cheap Gigabyte Z370P D3 ,but i what to upgrade that thing for a long time

Either the camera isn't picking it up, but that's some pretty quiet coil whine. Coil whine is usually a pretty high pitch squeal and is ten times more annoying than what you have.

Cameras (mics) are bad at picking it up, but higher FPS make it even louder, he used Halo 1 to demonstrate coil whine.

Which is why I am sceptical if it's even coil whine. It honestly just sounds like a bunch of fans running and a HDD spinning.

Oh, that's not a completely trash board, it's fine for I3's and low overclocked i5's mostly. As I said run stress tests and see which makes the whine louder. Try to run 3DMark 03, it's free, that'll run very high FPS and might make the coil whine really loud, which would be from the GPU.

Mine isn't like that but in RL it's pretty annoying when I don't wear a headset while gaming.

Naw that's coil whine, It sounds like that when you record it. A HD7950 I have has a pretty bad case of coil whine but if you record it you can barely hear it over the fans, yet to the human ear it's awful.

You still don't get my point don't you... You're just assuming at this point... You can't troubleshoot by just assuming things based on your own experience. You can use your own experience to lay out possibilities, but you can't conclude using them when there is no clear evidence to back it up.

I just told you I know coil whine sounds different on camera, and different cards sound different based on their VRM. I'm not sure why you're so agro either, but coil whine is the most likely cause, especially based on this. Also a lot of troubleshooting is based on assumptions based on previous experience, that's how people can often fix problems on the first try because they've seen it before.

My R9 380X had coil whine that sounds more like background noise, a kind of hazy noise because the VRM's run on a higher frequency, I think that VRM ran around 500Mhz, where as this HD 7950 sounds more typical because the VRM runs on a slower more typical 300 Mhz frequency. The R9 380X is very hard to make out on camera without decent sound equipment as it almost blends into the back noise but I can assure you it sounded awful to the ear.
