Lately my system just slows down horribly every once in a while. I looked in task manager and windows explorer was happily using all my cpu and most of my ram. I've noticed that it often happens after I access a specific partition and play around with some files there (mostly avi's and mpeg's) I know that the partition is often fragmented but I also defragment it often. I'm not sure if it's that, or what? anyway it doesn't sound right that explorer will use that much cpu just because the partion is a bit fragmented. Any ideas? I have to end explorer and restart it everytime if happens.------->rather annyoing.
