Each night, at around 4:15 in the morning, my XP machine emits two sounds. The first sound is either the default Asterisk or Exclamation sound (it's always the same sound, but I'm not sure which one it is), and it is followed soon thereafter by the System Notification sound. Just this morning, I heard the sound, and trotted over to the computer to look for any pop up balloons, app dialog boxes, etc. Nothing. I've gone to the Event Viewer, and there is nothing in any of the log files being kept (Application, Security, System, Internet Explorer). I checked the log files of my Antivirus program (Nod32, which is up to date and active). Again, nothing. Obviously, I'm concerned by this, because it seems to be a "scheduled" event, occurring each night as it does, but can find nothing to document what is causing this to occur.
I should also say that my XP box is running inside of a virtual machine. Running on a Mac using VMWare's Fusion. I've checked for a VMWare log file, but cannot find one on my machine.
So, is this the proverbial "ghost in the machine...?"
