Got a bit of a problem/concern with explorer.exe running the hard drive for a min or so after I log on, but I don't notice it when my son does. It consumes about 40-60% of the CPU under Taks Manager and that's the only app I see running for the most part. Converted the partitions to NTFS from Fat32 with Partition Magic 7, but everything was fine afterwards for quite a while. I noticed file indexing is marked ON under hard drive properties, and the ONLY other thing in sys tray upon boot is Norton AV 2002. Is there any services I should be checking or looking out for ??
