Try the Bitcrusher plugin.
But, dude, I get the feeling that to indulge yourself in your noob-ism will wear very thin very quick, and if your next question is where the Bitcrusher is and where you have to click and then how you can use it and what the controls do and after that how you can record what it does, then it might happen that noone will bother to read anymore let alone reply.
We can hold your hand only so far and ultimately you must decide on your own where to click, what to try and when to think.
How about getting some 1:1 tuition to get you up and running ? It's infinitely easier for one person sitting next to you than for a bunch of folks scattered allover the globe which try to read your mind.
