I noticed tonight a sound effect on my computer I usually would not normally hear, because I leave the volume turned down all the way..I was listening to XM radio via AOL...(which worked well for about an hour,then AOL had a hemmorage,and I had to sign on again)... I keep hearing a "creaky door" opening,a few minutes later it SLAMS shut!..it does it with the online radio off too,and once I heard a song playing for a few seconds..sounds like a door on the "Munsters" or something!.. Is my computer haunted??...or is it alerting me that "spies" are coming and going into my files??....should I be concerned??...any thoughts welcome!.
