If you still have old one, plug it in and use http://www.guru3d.com/files-details/display-driver-uninstaller-download.html to uninstall old drivers first.

Already did it like 5 times 😀 . Without the video drivers pc runs nicely and can start, but once i install drivers and run game, it immediately restarts and freezes again.
Yes i tried intalling newer bios version, change rams or remove rams. Nothing helps:C
