This will prove of interest with regard to CPU usage detailed under "Strange Services Information" on the Black Viper website:
"System IDLE Process: This is a generic process that is used when no other program or process is requiring CPU resources. It is not a bad thing if it is using 99% of your CPU! This process is a 16 k loop that the CPU processes while it is not doing "anything" else.
"If you computer is called upon to do any other task than nothing, the idle process allows that to happen and the % used will decrease accordingly. You can not disable the idle process. If it is using 97% CPU, which only means that the other 3% is used by real programs. If your idle process is constantly at a low rate (for example, 3%) something else, an application or process is using the CPU."
