Leopard won't start after install

[JuliusWang]

Hi Everybody,

 

I installed the AMD Leopord to the harddirve and no errors were shown during the installation.

However, for some reseaon, my system could not boot into Leopard. No error msg again, but just a Updating DVI pool...and a blinking cursor.

 

Graphic Card is 7950 GT.

 

Please offer me any inputs.

 

Thanks!!
