P5K-e screen switches off

[bingaling]

Hi all,

When I install Mountain Lion, it seems to be going well using this guide: http://blog.vondroid.com/?p=2631 but my dsdt.aml.

Then when it should go to the selection of language, the screen switches off entirely - the installation appears to continue, the hard drive is still running. This seems to me to be a graphics card issue. I've had the same card working on 10.5, 10.6 & 10.7, never really any problems. Any help would be appreciated

 

System is:

Intel Core2Quad Q6600

Asus P5K-e WiFi/AP mobo

Asus NVidia 9400 GT 1GB
