I have built my own computer about a year or two ago, this computer runs games at the highest quilty and such. But it has always had this problem where Valve games, Runescape and also Fallout games (anything with that engine) Will crash alot, with a black screen and tell me this. Display driver NVIDIA Windows Kernel Mode Driver, Version 327.23 stopped responding and has successfully recovered. At this point, I can not go back to the game and I have to go force quit the game. I have looked online a while back but did not find anything of use. I don't know if anyone here can help or had this problem and solved it. It is something with my graphics card and I got no idea what. I can play games at the highest just fine, only Valve games, Runescape and the Fallout/Skyrim engine. If anyone has any idea this would be nice as I got no idea.
