Hi Damon, First, get rid of Mcafee and get Nod32, and you will see your machine speed up immensely. Next, as I said in a previous message, buy Diskeeper, then you don't have to worry about defragging, just set it and forget it. By the way, Diskeep even has options for running a scandisk before a defrag if you select boot time defrag, which is an interesting option in itself, since it defrags your temporary swap file, and the Windows XP defragger doesn't touch that.

For some reason I can't complete a full defrag. It's a little confusing. It gets to around 10% and stops. Is there any reason why the existence of jaws, for instance, might cause this problem? I think it's a long running problem for me. My screensaver isn't on. But my Virus checker, Mcafee, is still on. Might this be the issue? Any system cleaning or tidying tips most appreciated.
