Hi, I posted this in another thread but thought some of you might want to read it and have a go at the remedy suggested: Noise from graphics card. I had the same problem - ATI card, MSI m/board and EMU audio card. Easily remedied: You simply need to screen the audio card from the graphics. I did this by fitting an old network card between graphics and sound card. I didn't install the actual software, just stuck the network card in the slot to act as a barrier. Works silently now. Try it out and if it works for you, spread the word. Lots of people online suffering same problem. If you use on board audio, not sure what you can do. I hope this helped some of you.
