I have just removed all the xtra stuff form my studio computer,IE., the 64mb vidio card, modem, network card, and went back to using everything that came stock with it. It cleared up my noise floor to almost nothing! I'm using the SB PCI512 card, so it's not totaly gone, but very acceptible. My question, has anyone else done this and got the same type of results?, And do you use your computer ONLY for audio, or do you also do the internet, WP, ect.? Just wondering.......
