You might try installing the Service Pak 3 and as Ron said your swap file might be to defragged. Under Programs go to Accessories,then System Tools, System Info. You will find out how much memory your system has and how big your current pagefile is mine is 1.96 gig. If you don't see any errors there try switch location of your memory...I had a problem recently that my computer keep telling me I was out of memory even though I had over 512 of ram...I switched memory...and the system is running like a charm.
