When I push the play-button the statrt screen (test screen) pops up and after a few seconds the start-up shuts down.

I've tried everything from dowloading drivers to updating the necesarry files.

When I first installed the game there was a screen that stated the video hardware could not be detected.

I did found the relevant details of the hardware when I ran the diagnostics.

Can someone help me?

Have you tried to change the settings manually ???
