I have noticed a very strange(high) amount of CPU usage during idle time in XP-Home. Is this the index service running? It only runs if the system is idle for more than a few minutes. If i move my mouse, it stops. I can see the HD LED just flying away while this task(whatever it is), is going about it function. I eliminated the obvious, Norton AV, Network connections, Etc. . IF i am real careful, I can bring up Task Manager, put it on processes, and see "SVCHost,a 12 meg task" running the CPU at about 40 to 60 %. ONLY during idle time(mousewise). Any clues?????
