Replying to What Can I do to Make my Laptop Faster?

Recently my laptop has been getting slower and slower to the point its a pain in the ass to even use.
I got it in the fall of 2005 so it's pretty old and performance has been lacking lately. I try to stay away from doing stuff that can really fuck it up like downloading music on limewire and a ton of porn.

So does anyone have some advice for idea that can speed this thing up a little bit, maybe things to delete or hidden folders where stuff is stored that I really don't need?

Thanks!
