Hi Saravanan,

using your code below

didn't give any errors on my side distilling it to the PDF. 
However the result is a white paper.

Try out the following code which gives a fine gradient such as 
wanted i guess.

\documentclass{article}
\usepackage[distiller]{pstricks}
\usepackage{pst-grad}
\begin{document}
\begin{pspicture}(0,0)(10,10)
\psframe[linewidth=0pt,linecolor=white,fillstyle=gradient,gradbegin=black,gradend=white,gradmidpoint=-.90,framearc=0](0,0)(10,10)
\end{pspicture}
\end{document}

Hope this helps,

Juergen
