Uncheck "Automatically manage paging file size for all drives" check box (for Vista and later)
Select the system drive your windows are installed on (usually it is C: )
Click "Custom size" to check it and enable aditional options.
In both "Initial size" and "Maximum size" type the value that is 1.5x of your RAM capacity. Example: if RAM size is 2GB (2000MB approx) type in 3500 MB
