For some reason, I am getting an annoying ALERT sound every few seconds without any popups or anything to explain why. What is it? I tried to look up a Fault Log to see what program might be triggering the sound but I can't find a Fault Log in Windows 7. I am using the full retail release of Windows 7 Ultimate. Purchased with cold hard cash. Any idea how to get rid of the sound? Or find out what is causing it? Thanks!
