Interference through speakers from wireless kb/mouse

[azibux1]

Hi all,

I'm getting a random interference noise through my headphone out on the front of my PC when I move my wireless mouse (Logitech Performance MX) or use my keyboard (Logitech K800)

They both use the same receiver and the keyboard one is only noticeable if I hold a key down. The mouse is annoying though.

This never used to happen and I've only just noticed it today

Anyone got any ideas on a fix?

Anyone got any ideas on this please? This never used to happen and isn't just related to the mouse/keyboard, the other day I was copying files and could hear interference being caused by the copy process, seems to be something with the PC itself

The extension lead powering the PC is directly into a wall socket, and has about half the sockets empty still so isn't under any load
