winXP pro performance graph

[Fredskin]

when I click on performance in task manager, it looks like an e.k.g., with cpu usage going from 1% to 100%, up and down, even with not much running. It used to stay at or around 6%. Anyone know whats up?

When you click on the Proccesses tab, select the CPU column to sort by utilization.

What process is using your CPU the most?

 

[Fredskin]

says SYSTEM IDLE PROCESS when it jumps up
