Every game quits unexpectedly

[gurcki12]

Hi guys!

 

I'm new here and i am german, i'm just 14, so my english is downright rediculous.

 

I've got the following Problem:

 

Every time i want to launch a game (like Quake Wars, Call of Duty 4 etc.) the game quits unexpectedly.

 

 

 

Here is another Screenshot about the report:

 

 

 

I tried to install 10.5.6 with iDeneb v1.4, same problem, now i tried with the new version of iAtkos (10.5.7) and i still can't play games.

 

I've got a nVidia G-Force 8600GT 512 MB and its 100% supported. I can post screenshots from System Profiler too, if i have to.

 

Could somebody help me please?
