How do I make my laptop faster to play the sims 3?

It's about 4-6 years old. It's in AMAZING shape. It's Vista capable. It's windows. I don't think I even have 1 gig of RAM. I do believe my lack of RAM to be the issue. If this is correct, how much would about 2 gigs cost? Where can a purchase RAM? Is it safe to install it into my computer... show more It's about 4-6 years old. It's in AMAZING shape.

Thanks in advance for your help and advice.
