RAM Issues- Running out!!!

I have been trying to render a short avi file with the motionmanager in SW 2008 SP5.0. See below for my workstationconfiguration-4GB RAM. SW crashes/closes after 20-25 seconds ofrendering the 1 min. video I need. I opened up my task manager toview the performance during the render and my PF usage hits about1.5GB and then SW shuts down without warning. My question is, canthis be a sign that windows is not using the paging file at all? Ihave it set 1.5 times the physical RAM (3.25GB x1024 = 3328 x 1.5 =4992 ). Can someone explain how this all works?
