i am concerned and curious. I recently built the rig outlines below and for the first month when idle 200-400 M of ram was always in use, even with task manager showing no running progs and no intensive processes running. This morning i find it's got nearly 850M of ram in use but nothing running. Anyone have any idea what i might be missing?

It is part of Vista's caching of most often used programs. If you open up a program that needs the RAM, it will evict the current cached data in your RAM to make room for your current program. This caching leads to a quicker response times.
