Crash during render a certain frame

Why do I keep having crashes when I render a certain frame? I tried with AVI and now PNG and they all cause Blender to stop working after a certain frame (I have 300 frames and it only goes through half of them, but it differs hugely on which frame causes the crash).

I’ve read somewhere that it could be due to I ran out of memory… well, why do I not have problems rendering with other 3D applications? Where can I set it to render to MY computer settings?

(I have 4 GB RAM, Corei7 and NVidia graphics card - 1 GB!)

Nevermind, got a solution: Found a decent build at Graphicall.org.
Renders just fine now.
