I will try to be as detailed as possible. When game crashes I don't get any error messages, the screen turns black and after 3-4 seconds the computer shuts down! I use the ATI HD 4850 version along with driver Catalyst 9.6 and in the game I use unlimited graphics.
At the beggining there was no problem but after some time, SF2 Europe started crashing when using some specific terrains like Korea or Desert without doing something. Simply after some time the screen turned black and the pc shut down. Later if the game was paused for more than 10-15 seconds, same thing, screen blacken and pc shut down. I decided to install SF2 Israel to see if there would be any difference. In SF2 Israel things were worse! (Same graphics selected) I couldn't finish neither one mission! Now I use only SF2 Europe and in every terrain I have this problem. SF2 Europe is updated to June 2010.
As described before, most times the game crashes when the explosion effects appear in the screen. In SF2 Europe I use the Hollywood explosions. As said above at the beggining there was no problem, after some time, game started crashing. I thought if there is some problem with the performance of the PC so I made a scan in the whole hard disc. No viruses no threats in general.
Any ideas?
