So my computer is freakin' ancient, a piece of ****, if you will, and I really want to get it's RAM up higher.

I only have 128 MB of RAM. Pathetic, really. But when I look around for cards, I can't find any higher ones.

My mother board only takes 72-pin cards last I checked, and I have no idea how to change parts on a mother board to take in more cards (I realise there is an option to change it, add more slots for more cards, all that fun stuff).

I'm stumped here. Are there any 72-pin RAM cards up there at at least 500MB? I think even 200 is enough, but still...
