System plays an audio file on it's own
First of all, I'm new here so -if I've posted this in the wrong place, please let me know so I can move it.
Approximately 4 weeks ago, my system was sitting idle while I was making supper. Just out of the blue it started playing an audio file that made me think the system played a warning audio of some kind. I could find no reason for it.
The next week, while idle, it played the same file.
The following week it played the same file on approximately 3 different days. It always only played the file 1 time.
Last night it played the same file 4 or 5 times and each time it repeated the file 20 times. the time between each time it played the file was shorter. 45 seconds between the first and second 40 seconds between the 2nd and third and so on until only about 5 seconds between the times. Today, I searched for every .wav file on my system and played it. That was 1,017 files but none of them matched the file that keeps playing.
I've ran Avast Pro, SuperantiSpyware, Malwarebytes and Spybot S/D. Everything came up clean. I've been running each of these everyday for the last 3 weeks.
I'm at my whit's end with this. Anyone have any ideas?
