I run a small (6 WSs & 1 P2P "server") network. When the machines are quiescent their CPU usage is between 1-3% *except* on one unit, a custom Intel 850 board & chipset I built, nearly identical to the others, which run fine. The problem is that for one the CPU is always running between 25 & 30% even with Norton and everything else off. The task manager shows no extraordinary programs. The line itself in Task Mgr has a S/N of about 10% or less meaning it looks like freshly-mowed grass with few spiikes or drops. Memory usage is about 25-30% also. I recently rebuilt the system from format C:\ and only have Office, Web and a few graphics pgms - same as the others I do AdAware every day and a full virus scan every week and all updates are in place. Just did FixKlez=0 Any ideas? Can this be normal? Is there some way I can check where my cycles are going? Sorry if this is too long. Thanks Robert Latven San Diego, CA

Have you tried disconnecting the machine from the network and see if activity is the same?
