Following my initial setup of Vista an optional video driver appeared in the
automatic update. I installed it and upon restart my computer would not make
it past POST. I tried booting from the Vista disc, then the system repair and
finally the system restore. Nothing worked. I had to do a fresh install of
everything.

Is this normal? I want to update the video drivers obviously, but at the
same time I don't want to risk having to reinstall Vista again.
