press WIndows logo key + Break key.
click Advanced tab, then under Performance, CLick settings, under Performace options, click Advanced, under Virtual memory, click change, select C drive, click Custom size, and enter the initial and maximum paging size (in MB).
For ex: if you've got 1 GB RAM installed, then initial size will be 2048 (MB) and then maximum size will be 4028 (MB).
The idea is you need to set the initial and the maximum paging size by multiplying it by 2 and by 4 respectively.
Hope that Works ! ! !
