Question Windows 10 laptop - Occasional chime outta nowhere... what could it mean?

[Muse]

My new Lenovo P1 (well, not the NEW 2nd generation, but a just acquired OPEN BOX), running Win10 Pro 64bit, occasionally makes a single loud chime (I have the volume turned up). I see nothing to suggest what it could be associated with. Not sure I should go into SOUNDS and turn everything off. But I sure as hell don't want to hear this noise pollution, which is exactly what it is if I don't know WTH it means. Suggestion?

Another person here posted this video link of all Win10 sounds that you might scan through in order to figure out what it is (he was having a similar problem and determined was apparently something related to Discord in his case):

All Windows 10 Sounds

If you are running a custom theme of some sort, you can also try temporarily changing the theme to see if the sound goes away.

It could be any program that's running causing the sound. I would start with the programs that run when windows starts up, and go from there.
