Vista Black Screen of Doom

I was working on a friend’s laptop yesterday, trying to fix the KSOD, i.e. Vista’s Black Screen of Death.  Unfortunately, this has become one of the more elusive problems with Vista.  This is especially true since it has multiple causes and therefore multiple solutions. Did you ever notice that just about every disease known to man start’s off with Flu-like symptoms?  Well, the KSOD seems to be Flu-like for Vista issues.
