Demo crash after load

[LeoKesler]

Hi,

I have tested the demo version but I am unable to play.

After the load screen, when the player show in the screen, with a dialog box (of the game) and a cursor (red circle) , the screen freeze and after some seconds, the screen goes black. The monitor dont go to stanby. The system stay freeze, dont power off.

My computer dont shutdown and I need to push reset button to restart.

The PSU is OK, because I have tested with latest 3dmark and the system dont power off (PSU with 550W) .

My system is: AMD X2 5200, 4Gb RAM, video onboard (ATI 1200 series) and Vista x64 SP1 (fresh install, from 5 days ago). I dont overclock my system.

About the onboard video, before the black screen, the game shows perfectly, with no errors or artifacts.

I am using the latest catalyst, 8.9.

Thanks for your help and excuse me my bad english.
