Hi I Have alreadylost my mind.
The problem concern the way of work that the 9800Gx2 is making.
After instal all drivers at new OS i instaled the Crysis to check graphic card.
I couldnt belive what happened.
After click shortcut Crysis the screen made Black. After few sec PC Rebooted.
I've tried a lot of different drivers and situations occured over and over again.
the strannge point is that GPU test are workin, 3d mark also.
I've the same probleme with an ATI HD4850 on a Gygabyte GA-MA78GM with Athlon X2 5200+. On vista when I launch the game, after appearing EA logo I got black screen and reboot.
I have tried all drivers and setting, but the some thing ... reboot.
So,I ran the bios setup and disable cool&quiet and virtualization parameters. And now it run very well .... no rebooting or hang .
