When ever I leave my desktop gaming machine and let it be idle long enough so that the screen turns off, I notice that it starts to become VERY ACTIVE! Soon as I move the mouse, the computer stops being so "active". The HDD is being continously paged and the CPU is being utilized to the point where I can really hear it spin up (is overclocked so when there is 100% utilization, it gets loud). I have kaspersky Antivirus so I'm not sure if that is it and I've checked to see if there were any processes that I was not familiar with that were running in the background but I can find nothing. Any idea on how I can spot which process is doing this/why!?
