Have you tried searching online. At the free software websites.
Usually you will find your wireless software even manuals to define
how to configure lost video cards.
If ye don't get your machine trashed by visiting a rogue site.
It's high time someone started searching and actively blacklisting
those. If google paid me, I'd do it.
I even came across one scam site that offered many pages of advice on
how to remove installed computer programs, except the content of each
page was identical except for the name of the software package.
Unhelpfully, this list they where using included some very trustworthy
packages - and the clueless visiting that site would come back with a
very bad impression of the real issue with their computer, and download
a rather bad trojan to 'fix it'.
