I Want To Start Playing Minecraft?

I want to start playing Minecraft, but I don't think I'll be good at it? I'm a girl, and my brothers play it, but I just find it so confusing sometimes! We have a.beginners guide, so that should help, oh and I also need help choosing a username for the site.

My Game FPS has dropped?

So I bought a new gaming laptop 3 days ago and I was able to run minecraft at a constant 60 FPS and BF4 at around 50-60 FPS. However, my laptop is now a lot slower after using it a lot and can only run both games at 30 FPS. Even worse… It fluctuates from 40-30-10-6-50 FPS and games are now unplayable! Is there a way of fixing this! Please help I spent £800 on this laptop and its not doing what I want it to!
