Buzzing noise in headphones when I move my mouse - changes when I switch power options

[Boraximus]

Hi all, so I was using speakers for a long time but I decided that it's time I get a pair of headphones. These headphones use the 3.5 mm headphone jack.

However, I noticed that every time I moved my mouse around AND/OR when there was high CPU activity, there was a high pitched buzzing sound ON TOP OF the constant static noise.

I found changing my power option in Windows from high performance to power saver almost eliminated the mouse part of the problem, now I only hear a different crackling sound whenever there's CPU load.

Do you think this is because of the PSU and will getting a new one fix the constant static and the changing buzzing sound? Thanks! - I'm also considering buying a new sound card, which one do you advise me to change?

Edit: I must clarify this issue is non-existent when I boot up in safe mode.

You need t understand that the noise you speak of is something akin to cross talk. You will experience frequency and buzzing from the audio equipment when you're powered off the onboard audio solution simply because the motherboard PCB is a noisy/busy environment(electrically speaking). Depending on the age of your platform the severity of the noise can be high or low and ofc will also vary from variances in QC per manufacturer of their motherboards.

You could use a ferrite choke to go at the source of your audio connection but that doesn't eliminate the issue. If the power settings change the degree of audio interference, then what I've said paints the same picture. You could for sure measure, make sure your BIOS is up to date as is your audio drivers.

Mind sharing your full system's specs inclusive of your audio equipment and a budget for us to suggest a sound card?
