All of those are "solutions" that people have tried. Every OS, vista, windows 7, mac OS, linix, even a beta version of Windows 8 are all effected. Reformatting and switching OS's has had no effect for 99% of the people. As for video cards the issue is effecting (at the last count someone did) more than 60 different cards (as reported on the forum). It's a broad reaching issue that seems to actually cause the most harm to the computers that should have the most ease running the game. There are people on the forums that have had their graphics cards melt when they are liquid cooled and should be able to run swtor at it's highest settings easily.
