My Mic causes interference

[Shalker96]

Hello, i have a problem, my mic from my headset (Genesis HX66) is causing some interference to my buddies when i listen to music, scrolling down on webpages or even playing for example Rust, LoL etc. This never happened before it just started yesterday, i tried lots of things like installing a new windows and reinstalling drivers but nothing works, its not my mic that's for sure because i tried it on a differente computer and it works fine. My specs are:

Intel Core Quad Q9300
4GB RAM
AMD HD 7870
ASUS P5KPL1600

Noise from the PSU or elsewhere on the motherboard is getting into your PC's microphone input. If you are currently using the front mic input, try using the rear one to eliminate the AC97/HDA header cables from the equation and see if that helps.

Another possibility would be to get a USB-based ADC and connect your mic input to that. I never was happy with the noise level on built-in audio mic input and I fixed that by using a headset with USB-based audio.

Forgot to say that my headset is only USB-based.

In that case, something must be dumping noise either on the 5V supply or ground and your headset's chip is picking that up. If you happen to have a snap-on ferrite bead, you could get a 3-6' A-A extension cable, loop it in the bead a couple of times. If your issue is common-mode noise getting conducted by the 5V/GND lines all the way to your mic, this should reduce it.

The last time I had a similar problem (noticing noise on the motherboard's audio output that I did not remember hearing before) and tried tracing it out to the source, it appeared to be related to the PSU's 5VSB output. The noise went away after I put in a new PSU. I put the old PSU in a spare PC and the 5VSB output died about a year later.

Nearly every component in your PC can potentially dump noise to ground or supply rails. In my case, it happened to be coming from the PSU itself.

Found a cable that was not connected properly, thanks for the help!

Which cable was that for curiosity's sake?

Sorry for the late response, I don't know which was it but it was one that came from the PSU so I just changed it with another one and removed that one.
