Processor running at 100% usage - Why?

[Andy]

Have a Dell Dimension 4550, P4-2.4G, 768 MB RAM, 60G HD,
running XP Pro. In running the performance monitor, it
shows my processor usage pegged at 100%. Does anyone have
a quick fix or things I can do to bring it down
to "normal" levels? This can't be normal. What would
cause this?

Thanks

What processes are taking the majority of that 100%
