Steddyman Posted January 4, 2007 Share Posted January 4, 2007 Hi Installed JAS DVD 10.4.8 onto my Asus P5W DH board complete with a Geforce 7900GTO (MSI) and it was working great apart from some screen corruption when scrolling the finder. I installed Titan via the appropriate directions and rebooted. Now after the desktop finishes loading I get this funny REBOOT graphical screen like the kernel has crashed. Searching the forums I see this is a common problem with the 512mb cards. My problem is how to I remove Titan without a complete reinstall? I tried booting in Safe mode (hold down shift) and it does go a lot further but I just end up with a Black Screen at the end. The system seems operational, but its not much use if I can't see whats on it. Is there anyway to remove Titan in this situation without having to completely rebuild it again? Or is there anyway to remotely connect to the OS from my other machine and remove it? Thanks Steddyman Please go easy on me. This is my first experience of the Mac and OSX86 Link to comment https://www.insanelymac.com/forum/topic/37675-help-titan-on-512mb-nvidia-card-now-no-boot/ Share on other sites More sharing options...

Steddyman Posted January 4, 2007 Author Share Posted January 4, 2007 Sorry for being stupid, but how to I boot with -S? I tried holding down CTRL-S at startup and that did nothing. Still got the reboot message. I select Mac OSX from my Vista dual boot menu and it goes straigt into the Darwin boot loader then seconds later into the white graphical boot screen. I don't get a prompt to type anything anywhere. Thanks for the detailed info on how to remove the extensions, it is appreciated.

Steddyman Posted January 5, 2007 Author Share Posted January 5, 2007 System is now recovered. The only problem I seem to have besides speed is that scrolling or dragging windows always corrupts the screen. Is tehre any way at all to get my 7900 GTO working better without Titan? Thanks in advance. Link to comment https://www.insanelymac.com/forum/topic/37675-help-titan-on-512mb-nvidia-card-now-no-boot/#findComment-268927 Share on other sites More sharing options...

Steddyman Posted January 5, 2007 Author Share Posted January 5, 2007 Does your 6600GT only have 256MB of memory? It seems to be 512mb that causes the problem.

Steddyman Posted January 5, 2007 Author Share Posted January 5, 2007 I fixed the problem by removing titan.kext and also geforce.kext. With geforce.kext there is no longer any screen corruption and it all seems to work fine.
