I am not sure what the problem is. You say Oracle is using about half the memory in the machine. You say you have memory problems. What is the memory problem? Very unclear what problem you are having.

On Windows machines if you allocate more memory than you have RAM then you will swap some of the memory pages to disk (in the pagefile) If you rarely access that memory than things might not be too bad. If you keep accessing memory that has been swapped to disk - and force other pages to be written to disk - then you can have the machine grind to a halt as it tries to use disk as if it were RAM. This is true of Oracle using the memory or Word or any program.

Our crystal balls are in the shop, you need to enlighten us as to what is going on more specificaly. My first bit of advice would be to NOT disable the pagefile.
