When you ran Windows Repair did you only select the options in the list I gave, none of those options could have deleted the minidump files, so I am not sure what has happened unless you also selected remove temp files by mistake. Likewise with the changed behaviour of Internet Explorer, if you also selected the IE repair option it will have reset it.
All we can do now is wait to see if you get any more BSOD's.
As for the Graphics driver I would first try reinstalling it from the manufacturer's site.
