Can I make my Samsung Series 3 Notebook run better?

I have a Samsung Series 3 Notebook (if you haven't already notice) and I want to play games on it. It has a core i3 intel processor, windows 7, with 2gb ram. And I want to play minecraft and record it with out lagging. So does anyone have any ideas or solutions on how to make it better?

Added (1). And it can't cost me any $$$ because I'm low on funds

RAM would be your 1st check - try the link to see if you can & how much RAM you can install

then it would possibly be upgrading the graphics
