What do you have your paging files configured to? Do you have it configured so its equal to 1.5 times the total RAM as Microsoft suggests or do you have it turned off?
I have it set manually for max=min=roughly 1.5 times physical RAM. I have 4GB RAM and a 6.139GB Page file on a seperate RAID container from my system drive.
max=min=1.5 x RAM
