Some tips:
I had trouble with them intro movies in
\Data\Movies\Intro
After deleting them game boots allrite.
That was an issue with some codecs, I've read it somewhere in teh internets.
You may want to move those elsewhere just to test how it goes.
Also, when installing them drivers, using a tool that removes the crap
old drivers leave behind is what I do.
Driver cleaner, or whatever it was called.
I think
guru3d has it atleast.
