Where can I find puzzles?

Okay, so I'm really new to everything about computer chess.
I've never used engines for any reasons, nor any computer programs, but I would like to try them out to solve puzzles.
More specifically, I would like to find programs that have different kind of puzzles in them, as I'm not interested in analyzing games or playing against a computer.
I know about sites that have tons of tactical puzzles (like chess tempo and others), but I'm looking for these "old school puzzles", the ones that have different outcomes; those that aren't about winning a piece or forcing a checkmate in 3, but actual problems made by composers.
I have a few books that have some of these good old problems, I just thought it'd be much simpler and easier to solve these in a program rather than setting up a real board.
Any of you know some programs that have these kinds of puzzles "built in"?

Not sure I get you. If the point isn't mate or winning material, what would be the point? Making a pretty pattern with pawns? 

// Well, one site with old school problems is Edward Winter's Chess Notes.

Well, let me rephrase it, English isn't my first language. I was looking more of let's say, positional studies, if you like, like those famous old problems that have more positinal play in them rather than a forced checkmate in 3. But I'll take a look at these, thank you both.

For a guy who's first language isn't English you are doing rather well 

In Walmart. They have jigsaw puzzles all the time. All joking aside, if you're looking for chess puzzles, try: chess365.com. I used to go there, they should still have them.
