After Updating to 10.6.7 I Get Blackscreen After..

[janovic]

Good Afternoon folks, I few weeks ago I updated my mac from 10.6.2 to 10.6.7 and after I get the apple logo I get a blackscreen. I'm running on a GeForce 9800GTX +

Does anyone know if there is something I can do to get the video working properly again?
