okay, I put this in the other thread but will put it here, too. If you are looking at the 'system idle process' in the processes section and the CPU is around 90 - 100%, thats NORMAL. If you are in performance and the CPU usage shows that high constantly, then there is a problem. The system idle process CPU time is basically telling you how much is available. The higher the better (a little more involved than that, but thats the gist of it).
