I can't really help you without seeing your scene. I can just give you the clichaswer like use less reflections and transparant and glass objects. And keep your scene-files as compact as possible so your computer doesn't start swapping (swapping really slows down rendering, I once monitored processor-activity and it was 100% while using RAM, but when my computer was swapping the harddisk was working at 100% and my processor at 3%(!), it was just waiting for my harddisk). If you e-mail me your scene I might be able to give more specific solutions to your problem. My e-mail adress is: rayraz.rv@hccnet.nl and I've got an ADSL (broadband) connection, so I don't really mind downloading large files.
