Raghu,

Do not depend on Performance Monitor alone for your CPU statistics. At least in NT4, it quite often reports 100% usage with nothing going on. Right now on my workstation I have one little Access database open with no activity. Performance Monitor is saying CPU is at 100% and has been for the last 5 minutes.
