Which Windows 7 log file contains audio jack connections/disconnections information?

I have a problem with my new computer. Sometimes a toast is displayed telling that headphones has been connected to front panel of my PC case, and i never connected a headphone to that audio jack connector. This front panel is connected to the motherboard so it is directly related with the integrated sound card of the motherboard. I tryed formating, with two operating systems (win 7 & 10) and same problem.

There are two posibilities. The motherboard can have a problem or the pc case can have a problem. I connected the front panel of the pc case to another computer with windows 7 and i will leave this all the night on. I need a log file or something to check the next moing if an event of connecting/disconnecting a headphone to the front panel has bent detected or not.

Exists a log file in windows 7 for that?

Thanks
