yes, i run sfc/scannow nearly 4 times. for first 3 times it said something like no corrupted files found. by fourth time when i run it resulted "windows resource protection found corrupt files and successfully repaired them" and i did system reboot.
But later it got crash again, same fatal system error. then i run driver verifer. Its still in enable mood, i have not yet disabled verifier.
Im not able to identify where that resulting DMP files are?

They are in C:\Windows\Minidump

I had same error. Cause was overheated graphics card. I cleaned graphics card fan and refitted fan with fresh cooling paste. Then problem solved, could even overclock GPU further then before.
