Thanks, everyone, for the advice!
My system is a Dell Dimension DIM9100 with the P4 CPU @ 3.20 GHz that runs windows XP. The VMD startup info was attached below. If it is a graphic card/ driver issue, what do I need to replace to make it work?
Thanks again.

the white surface is most likely due to the fact that your graphics
card and/or its driver do not support surface texturing. please post
the startup message from your VMD command window.
