Hey good people, what does it mean when u hear a clicking sound on a regular basis on a desktop computer. Let me explain futher. If any of u know how the click sound of a page reloading on something like yahoo sports ticker or something of a sort. That's the click i hear constantly after i boot up my computer. Could it be something is running a refresh without my knowing? and if so, where would i look to check. I have an e machines desktop running windows xp
