I have WindowsXP SP3, Dell Dimension 4700. For the past few days there has been this beep that is fairly loud and very annoying. I have searched this forum and did not find an answer that is like my problem. I have no idea what is causing it. It is there no matter what I am doing, browsing or playing games, etc. Just always there. Please help. I have no virus. Secunia says that my machine is 3% higher score than the average in Tex.
