maby you need to increase your virtual memory
.. i had the same problems before.. firstly the hard disk memory.. then the graph. card.. then the ram memory.. then i came up with the virtuall memory increase.. asked around and poof.. gone were the problems..
heres the info on how to do it.. and it doesn effect other programs.. at least.. its doesn with me.. or with the people that i helped with it so far..
heres the things
click desktop then my computer (or my computer if you have the thing on yer desktop already, anyways.. go to my computer... )
on the left side of the screen it says view system information click it
now the computer gives a new window with lots of tabs,
system restore, automatic updates,remote,general,computer name,hardware,advanced
click the advanced tab
now you see a part with performance with as a lil help underneath it : visual effects
click the dialogue box beside the thing that says : settings
again you get another window with 2 tabs with 1 of them saying advanced and again you have to click advanced
now you see something with process scheduling and virtual memory @ ###
underneath theres a part that says custom sixe and 2 boxes where you can fill in numbers..
you need the second 1 that says maximum size
change the maximum to 9999 and it will give you a prompt of what the true maximum can be
now input the maximum size figures into the maximum field thing..
press apply or ok and the computer will tell you to restart ( if not.. still restart it.. )
press yes and the restart commences.. so be sure to save your files before pressing yes / oke
the computer will restart and the operation has been finished.
the effect will be reall noticeable when the computer is restarted...
hope this helps a bit...
