Graphics problem hd3870

[popposlusk]

Hi, I have been trying to install Leopard 10.5.2 on my PC using both Leopard-10.5.2-AMD-EFI-Rev2.iso and 

Leo4All-10.5.2 Universal AMD/INTEL[sSE2/SSE3]. I got the same problem with both releases. It installs sucessfully

and after the computer has rebooted I see this:

.

 

The harddrive keeps on working for a short while after I see the screen and when moving the

mouse some pixels are moving in all the small squares allover the screen, so my computer isn't looked up,

it seems just to be some graphics error.

 

When pressing the power button, my harddrive turns off but the rest of my computer are still running and the screen

looks like this instead:

I know I can't expect "stand by" to work, I just tell this because it might help someone telling me what's wrong.

 

My hardware:

K8N Neo4-F (nForce4)

Athlon 64 X2 3800+

Sapphire Radeon HD3870

3GB RAM

 

I have tried both with and without the hd3800 driver, and got the same result.

What am I doing wrong? suggestions?

 

I have sucsessfully used Mac OSX 10.4.8 from JAS on this hardware without any tweaks (did not try to install a hd3800 driver)

 

Sorry for my bad english  I'm swedish

Boot with -s at the Darwin prompt and mount the Leopard partition and rm -R /System/Library/Extensions/ATI*
