I need some help here to fix some issue in my system. Every time I launch a game I have a blue screen with error dxgmms1.sys. I read on internet that it was because of Direx X so I reinstalled the same but work at all. Right now I am working on Windows 7 and I have direct x 11 and on the same hand my GP supports 10.1 version of Direct X also. I have another error with the blue screen always kl1.sys. This looks like some problem with Antivirus.
