Sounds like you could use some more RAM, but you may be having something running awry on your PC causing issues or a hardware issue. I've got 3 vista PC's and all run very fast, but all have at least 3 GB of RAM.
Do you know if you have the 32 bit or 64 bit of Vista? I was told that currently the 32 bit version only supports 3 GB of RAM, you can have more, but it doesn't see anymore that that. Supposable they are coming out with a patch for that.
