Do we really need to clean the gold fingers of our video, sound card, ram, etc if you find any unusual marks or oxidation? This is something I like to know more about because its not something that I've considered in sometime now. From what I know those gold fingers are suppose to be oxidation proof. I was having sound card problems and couldn't solve it. So as a last resort I took out the sound card to inspect it. I noticed something on the gold fingers that dulled the shine. It was some sort of residue or film. I couldn't tell you what it was. However, I found that cleaning the gold fingers of my sound card has fixed the problem I had with it by wiping them clean. I wouldn't recommend doing this unless the equiptment in your PC case is at least 1 year old. Anything new shouldn't require this IMO and you are experiencing a problem in which this would be a last resort. Does anyone have any information about this?
