cpu usage

I have windows 2000 pro and my task manager says that the system idle process is using up to 99% of my cpu usage. I tried defraging but I still practically freezup. the graph says that I'm only using like 4%, but the processes tab says otherwise. What do I do!?

 

You want the idle process percentage to be high. That means your computer isn't running a lot of junk in the background. This isn't indicative of a problem. It's a sign of efficiency.

 

The systems idle process display is showing that the computer is basically at rest and not doing much of anything.

The graph under the performance tab inversely reflects the system idle process. Meaning if the system idle process is showing 96% then the performance tab should show 4%. Keep in mind that when you switch from one view to the other, you will see a small spike in the performance tab.
