Freeze after start

[mudemi]

hi guys,

i am searching since 2 weeks for a solution, but i am getting really desperate.

at first here my system:
laptop asus z92km (barebone a6km)
amd turion ml 34 1,8ghz
1gb ram 400mhz
geforce 7300 go

that should be the most important things.

now my problem. my system freezes after few seconds after booted up. i have found out that there is a problem with gfx card. when i start without any driver and injecter, there is also no freeze, but of course just vesa mode (1024x768, no qe, no ci).

the weired thing, under tiger my geforce go 7300 worked fine, with qe and ci and resolution change (native resolution is 1280x800).

now i have tried out different leopard install versions and nearly every injecter i could find via google (nvkush,nvinjectgo,natit,titan,nvdarwin) i also added manual my dev id 0x01d7 to the proper, but everytime i get the same proplem. after few seconds using leopard with qe and ci my system crashes. keyboard and mouse dont react anymore.

anyone any ideas, i could try?

i myself dont know anymore what i could do.

could there be a problem with bus speed, or acpi or sth like that. i noticed that tiger shows in system profiler my bus speed correct with 400mhz, but leopard shows just 200mhz. anyone knows how to fix this so i could see if this is the problem.

lots of thx for any help, any ideas.
