Screen Saver Does Not Come On

RE: Windows Vista Home Premium on a Toshiba Laptop

The screen saver does not come on, and the hard drive always seems to be

doing something, other than sitting there quietly when I'm not doing

anything. Could there be something running in the background that keeps the

hard drive busy and thereby not allowing the screen saver to come on?

I know of MSCONFIG to see what starts up, but is there a system utility that

can tell me what's up and running that may be causing the hard drive to keep

working away?

Thanks
