vista is not shutting down after installing intel draphics driver

[san_crazy]

I have purchased a dell laptop that came with Windows vista home premium. everything was working fine at first but since, when I installed graphics driver to get the better video quality it is not shutting down.

how can i fix this problem?

Revert back to the old drivers...
Where did the driver come from ? ?

[san_crazy]

I have downloaded it from dell web site and it has enhanced the graphics quality.
I have a driver  CD that came with laptop but it doesn't have the graphics driver thats why I have downloaded it from dell site.

what should i do to solve this problem instead of uninstalling it?

It didn't enhance the graphics quality.

And if it did a fat lot of good it'll do if it shuts down.
