and I'm nervous about it. Here is the history on my computer it is 18 to 20 years old and lately the harddrive has been making a very loud noise while freezing up on me a lot my computer is running like a very slow snail I don't want to do a defrag on it because I'm afraid that it will mess up the harddrive even more. What should I do?
