You probably know this, but you are woefully underpowered with RAM. Under Edit -> P)references -> Memory & Multiprocessing, make sure multiprocessing is turned off. With your setup, don’t turn on any other applications or software when rendering, you barely have enough to run AE and your OS at ths same time.
You could attempt to isolate the problem by turning off 1 layer at a time and set up a render to determine the cause of the problem.
If all else fails, collect your files(under the File tab), bring the project to somebody who has a more powerful system and have them render it.
