Smoke simulation problem

I have recently tried to do some smoke simulation. But things are not working.
Whenever i assign a cube as domain, it turns completely black, nothing appears thereafter. I cant see the flow object inside the domain even in the wireframe mode.
Plz help me guys.
iS there something wrong with my system…?
I use INTEL PENTIUM DUAL CORE processor with 2.00 GHz speed.
my computer is 32-bit
And I use Window.

          I am attaching the screenshots.


This is the third thread you’ve created asking this same question !

If you want a thread moved report it (small triangle icon in bottom left corner of post) to the moderation team asking for it to be moved.

What you could give a try is put your mouse on the 3d view screen
then type space
in the search dialog that apears type quick
next choose quicksmoke

This result in a quick smoke setup, if that doesnt work for you then check your video drivers or at least attach you blend file.
