System Idle Process taking 99% CPU?

Just wondering if this is a normal occurence in WindowsXP. Just having a look at my processes and was wondering why the System Idle was using between 70 and 99% of my CPU. Maybe this is normal? Maybe not?

Thanks!

Because the system's idle maybe?
 
That's CPU TIME not CAPACITY. If you look at the performance tab, you should see that you're floating between 0%-4% CPU utilization. 98% of the time, your CPU isn't doing anything, so NT-based OSes issue HALT commands that make the CPU do nothing. Bonus feature is that it'll run cooler as a result. (That's what CPU Idle or Rain did for Win9X OSes, issue the HALT command that they didn't have built in.)
