Bump Cmon Blizz! I wanna be able to play on higher than minimum settings for more than 20 minutes.....fix the problem!!

I'm getting the same message.... My rig is : AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ 2.6 GHz 2.00 GB of Ram NVIDIA GeForce 9800 GTX/9800 GTX+ Virtual memory is at 1000 initial, 10000 max No matter what graphics setting i use, it runs out of paged pool memory, though at lower settings it takes longer. Is there a glitch in the system where it doesnt purge the memory after its not being used? Edit: also im not sure if it is an attributing factor but i am using windows xp
