What I am experiencing is that from time to time, mainly just under normal surfing conditions or low load conditions, the entire pc stops responding for 1-10 seconds. Just before it starts to respond again, I hear a little click from the tower (Mozart Tx case) and everything is working again just fine. 
I am currently running an X2 6000+, 4gb ram, two 1tb drives, one 160gb, one 500gb, 8800gtx, 650w Corsair ps, on a Gigabyte board (forget the exact model) with the cpu and gpu under water. All stock speeds, not OC'd at all. Also I have my OS on the 160gb along with most of my programs with the two tb drives as media storage and the 500gb as a backup drive.
I check my temps, and everything is within range, cpu around 35-40c and gpu around 40-45c.
Does anyone have any idea what might be causing this? It's more of an annoyance rather than a problem, but I would like to understand what is causing it.
TIA
