I am trying to Render to Disk even the simplest scene: a cube rotating, nothing else !!!! When I start render to disk, as soon as it starts it hangs. I tried BMP,PNG, Qt ..... even at very low resolutions .. nothing works

I did it on my Toshiba Qosmio x70 and x75 computers, it doesn't render.
I tried on desktop computer with Quadro Graphics card on a computer which is $5500 .... and again nothing works.
Why I'm not able to record anything ?!?!?!? Is there any configuration in the card that I shall disable or anable?!??!
please, please help....
I can't make any type of demonstration. I am using Ventuz 4 and V5 designer.
I am using SSD drives.
regards.
