Video Problem in HP-D530 PC VGA DRIVER

I bought a HP-D530 chipset and windows XP install on it that VGA graphics, color, and videos are running and working perfectly then I decided to install windows 7 on same pc no installation and running problem but I just hit the Mediaplayer and I open a *.flv video it is running smoothly but a green strip line appear in the middle of running video.

So my question is that what is the problem with VGA driver or hardware?
