Question buzzing noise coming through earphones

[scott123456]

So I have a new computer and I have installed a fresh copy of windows, but there seems to be a buzzing noise coming through my right earphone, I have tried both audio jack ports and its still there. What I have found out is that it only does it when my computer is doing something, if it's just idle on the desktop with nothing open it goes but if I open programs or videos it starts up again.
If I uninstall all the audio drivers it goes so I'm not sure what it could be
I'm thinking it might be getting interference from the hard drive but I'm not 100% sure
or it could be coil whine or maybe a power issue??
I'm lost as to what it could possibly be at this point any help will be appreciated. Thanks

Sometimes it can be residual vibrations from a fan (usually the PSU) that cause a static sound through headphones.
This may also explain why you only hear it when your PC comes under load.

Ive give the fans a good clean and its still the same

I don't necessarily mean that a clean will resolve it.
I mean as in a small level of coil whine or friction on a bearing of a fan can cause a vibration to cause a sound through you headphones even though we can't hear it normally.

Not always the case, but is quite common.
