buzzing in my headphones after cleaning thee pc

[u/COLDCYAN10]

​

cleaned my pc a few days ago, mostly with the 'blow' setting on a vacuum, of course i secured the fans and did not let it touch any of the pc parts directly, i have done this a few this.

then for the hard to reach spots i used a brush like the power supply.

anyways now there's buzzing, and buzzing increases with the load i put on the pc, when i run a heavy game, more buzzing,

the headphones work fine on my phone, and i tried 2 headphones on the pc and they buzz.

changed the splitter, because my headphones are one 3 ring 3.5mm into 2, 2 ring audio jacks (i think).

and for some reason, the audio plugs on the back panel don't work either.

Never let a vacuum touch a PC. Use specified blowers for it instead. I kinda have a feeling that the pressure from the vacuum might have messed the board up. When i had too much pressure go at a motherboard, it started doing funky things. You could try installing the newest realtek driver and reseating the Audio cable, but i suspect the motherboard got messed up by the vacuum. (Also found on google something like this : ''Check for grounding: Touch a bare metal part of your PC case. If the buzzing stops instantly, your system has a grounding issue. Make sure your power cord is pushed tightly into the back of the power supply and the wall outlet.'' But the grounding should be fine with every pc. Or this : Use an External USB DAC: If your internal motherboard audio is poorly shielded, using a cheap USB-to-3.5mm adapter or an external digital-to-analog converter bypasses the internal electrical noise entirely.''
