Screen keeps flashing after installation AMD

[AlexCaz]

Hi,

 

I just installed Zephyroth 10.5.2 without any errors. After rebooting for the first time, I see the Mac logo on a grey screen then I see a grey screen with a cursor switching to a black screen indefinatly. I am running on :

 

Amd x2 3800+

Asus a8n-sli deluxe

Kingston hyper-x pc3200 4 gig

ati x800 xl

 

i installed the ati x1900 drivers on a Slave HD disk formated to HFS+.
