What version of AE?
What system specs?
Output settings?
All of the above will be helpful to know if you want an answer.
Turn OpenGL off.
Make sure you have enough RAM per processing core (2GB/core)

its AE cs4
running windows xp on a mac with boot camp, it has 3gigs of RAM and a 2.80GHZ dual core processor, yes i have turned open GL off and i have set it to purge every 10 frames in make movie since i anticipated the RAM might not be enough, and the output settings are to render as a h.264 PAL high quality widescreen, if you require any more info just ask, i greatly appreciate all your help =]

[Sumit Mehta] "the output settings are to render as a h.264 PAL high quality widescreen"

This could be your problem. You should avoid using AE for compression. See Dave's Stock Answer #3 below for more.

If you anticipate the render being difficult on the computer, I'd recommend rendering to an image sequence. Unlike rendering to movies, when an image sequence render fails, you can resume the render where it left off.

Quoting forum leader Dave LaRonde:
Dave's Stock Answer #3:

Don't use AE to compress files for final delivery. The various compressors are there only to make quick 'n dirty files showing a project's progress to producers, clients, the kids, etc. AE is incapable of doing multipass encoding, a crucial feature that greatly improves the image quality of H.264 and MPEG-type files in particular.

Render a high-quality file from AE, and use a different application to do the compression. Popular ones are Adobe Media Encoder, Sorenson Squeeze and Apple's Compressor, which comes bundled with Final Cut Suite. Even compressing in Quicktime Pro is better than compressing in AE.

Making good-looking compressed files is almost as much an art as it is a science. It is NOT straightforward at all. I recommend asking a few questions at the COW's Compression Techniques forum.
