Strange windows clicking/ad sound from system

Every 2 hours or so, there would be a mysterious windows 7 clicking sound coming from the system sound, the way to describe the sound would be whenever you browse through your C: drive, every folder you access will have the default window click sound depending on the theme you're using.

It starts off with my cursor doing the refresh/loading animation and a few seconds later it produces the sound, is this some sort of trojan/adware/keylogger?

I really need help here.

Thank you.
