I SOLVED MY PROBLEM.
THE SOLUTIONS WERE THESE;
I created a new log from Registry, I am putting the path of it.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers (Make sure that GraphicDrivers folder is left clicked from the left side.
After that a new window will be opened at right.
In this path from the right side, right click>new>DWORD(32BIT) VALUE
Rename the value as TdrLevel (Make sure that T and first L are capital letters.)
The value data must be at 0 (THIS IS IMPORTANT.)
I reverted my graphics drivers to older version and did a clean setup. After I updated it to current version with a clean installation.
I did an reset to my Bios to return default settings.
After these steps I had no crashes. I hope this will be helpful to you guys.
Cheers.
