I'm giving a computer to a friend and can't defrag it. About a year ago windows defrag quit working and I switched to dick keeper lite. The computer is running very slow and when I ran defrag it had over 4000 fragments before defragging. After defrag it said there was only 1, but the system was still slow. I analyzed the drive again with disk keeper and it said there were over 4000 fragments again, what can I do to fix this? Thaks for all the help.
