>>>I have a NEC notebook PC that seems to have slowed down lately. I used Nuts & Bolt to monitor the PC and found that CPU usage is high (around 20-30%) even though there is no process going on (i.e. no programs running in back ground or foreground) There is no virus on the system. Is there any utility that can tell me what is occupying the CPU?

>Thanks for responding. I had a look at Process Viewer. It listed all the programs that were loaded in memory, but how do you know which one is actively taking up the CPU time?

By looking at the Processor Time, you can get an idea of which ones are taking up a large chunk of time. Once you have this narrowed down, you can Refresh the list several times to see which one is currently taking up all the time.

Another suggestion and I don't know if it will work because of the differences in OS, is to to find someone with NT installed and get a copy of Taskmgr.EXE. It can be used to display a list of all the processes running and sort on CPU Usage.
