I'm afraid that mining is not recommended for you with little knowledge about mining, you should only engage in mining when you are well informed.
Mining isn't rocket science, so I don't really agree. In fact, the point of mining is that anyone can and everyone should do it to split the load around. I would, however, advise against mining bitcoin without significant investment (and therefore knowledge). Start with mining a crypto that uses your GPU.
Ethpool has an FAQ (
