You can also try to buy another 2 GB of RAM and see if the problem 
persists. On a machine with 4 GB of physical RAM, a 32-bit OS usually can 
see ~3..3.5 GB free. I even think that if your OS supports page files, it 
doesn't matter if the memory is on chip or disk - if the memory is split 
3/1 for processes and kernel, you should be able to allocate 2 GB easily.
