When I leave my PC on for a few minutes and I leave, the monitor shuts down. When I come back, I notice that the Hard Disk light is either 'on' or blinking at a furious pace. As soon as I touch the mouse or the keyboard, the light goes back to normal.
So something is stressing the hard disk while I'm away, and because it is already a one year old laptop, I fear for the safety of the disk. How do I find out what the culprit is and disable it?
