You don’t have enough RAM, 2 gigs isn’t enough to share between AE and your operating system. Few different things you could try. First, while holding down “shift” go to the edit menu -> Preferences. Now choose the heading “secret” and disable layer cache and set the purge frames to something like 15. You might be able to finish your render this way.
Alternatively, you could just render your sequence to a TIF sequence. And if it crashes, just go take a look at the last TIF rendered and start from there. Soon enough you will have the entire thing rendered, then just bring the TIF sequence into AE and render that to your final format.
Lastly, under the file menu, you could save & collect all your files, put the entire project on a thumb drive and find someone with a beefier system who could render out your final project.
