I have a late '08 Macbook Pro with 10.6.8, 2.4gHz Intel Core Duo Core Processor, and 4GB Memory at 1067 Mhz DDR3

I have Pro Tools 9

I was wondering (I don't know TOO much about the internals of computers), but would I be able to purchase more Memory and a new internal Harddrive with more RAM and put it in? Or would that be a bad idea since my computer is old (and starting to show with things like freezing, shutting down, over heating, and screen blinking)?

Thanks,
