Hi, I am facing problem with BSOD. Its just if I play a game in 3-4 minutes game freezes and crashes my system to safe start. Same does not happen on 1080p movies on VLC Player. I already had updated nvidia drivers. Then felt may be new drivers are unstable so also went to safe mode installed some really old stable driver. However problem remained the same. I also did memtest. I am sorry I ran out of patience but post 2 hrs also it showed new error. also there are no artifacts as such on the screen. My System : Intel Core I7 920 Gigabyte X 58 USB3 Gskill F3-12800CL7T-6GB GTX 580 Twin Frozr II Xonar Essence ST Corsair HX 850 Windows 7 Ultimate 64 bit If I have not filled in info as per desired format, do let me know if something I need to add. Sorry n Thank you for the same.
