Well, I reinstall my Vista ...
all latest drivers and system updates, and still the same problem ..

So, its definitely GameGuard problem (or loader)

But i found couple months old backup partition, and it was ok .. (thats why i decided to reinstall system)
That means, problem might be in colision with some of Vistas latest updates.
unfortunately i cant get more info about that, because i already use that place for new backup.
