I'm running Windows XP Home SP1 with DirectX 9.0b, NVidias
certified drivers v40.72. It worked well a long time but suddenly
some games was minimized and locked. Then "ctrl+alt+del" is
the only way to close it. Also when I do the Direct3d test inside
dxdiag, I just gets some error messages: You have stopped the
test by pressing a key... but I did not! I'm really sad because
nothing seems to help. I reinstalled DirectX 9.0b and NVidias
drivers. Then all the games and the Direct3d test worked.
But after next restart the problem was back again...
Do anyone know how to solve this?
