I've taken your advise and purchased the XP Home Edition Upgrade today. I hope that it performs on my computer as fabulously as it has on yours. It has been very frustrating not being able to render large images in Poser. Interesting enough I exported the same scene to Vue 4.1 and it had no problem and didn't choke at rendering my Poser image. In fact I like Vue's light set up much better than Poser, Poser's got no point lighting and point lighting works really well for inside scenes. If others have the same problem as I did, but don't want to switch OS and have Vue 4 also. I reccommend rendering in Vue. It took 3 and a half hours, but hey I got the scene I wanted with the lighting I wanted.
