Lately, when I do shutdown on my Windows XP Home machine, the computer makes a beeping noise. It does it when the screen turns to baby blue and says Windows is saving your settings. The computer turns off fine, and boots up fine too. I'm just trying to find out what's causing this beep. Could it be an error message and Windows is just ignoring it? How do I find out what's making the beep? And how to fix it? Thanks in advance!
