Right now I'm playing ToMI chapter 4 and approximately after 15 minutes of smooth game play, at ANY point of the game, my screen turns black (and reads: "No signal") while I can still hear the sound of the game. But, it is very clear by the sound I hear that the game itself also get stuck. Ctrl + Alt + Del does not work as well Alt + Tab or anything. The computer just dies or something like that. I have to shut it down by pressing the on/off button for a few seconds.
I had no problems with episodes 1 and 2. The problem did appear at episode 3 but I had some hope it won't happen with chapters 4 and 5 (Which sadly it it). I did not change any thing in the computer between the episodes.
My operating system is Vista 32 bit. I have installed the latest drivers - video card is the 'Nvidia GeForce 9600 GT'. Tried running as administrator and compatibility mode of Windows XP. Tried Full screen On/Off and also playing with different resolutions. Nothing helped.
I am sure it is not a problem with any thing else because other games work perfectly (Just played Dragon Age for 3 hours).
Thanks in advance for any help or for even just reading this ^^
