I don't even need to debug 116. It's either video card drivers or GPU. We know it's NOT the board, you've been through two. Try different video card driver versions first, such as beta, or go to earlier versions. If you still crash, uninstall video card drivers, shut down, remove video card, install integrated video card drivers, and see if you don't crash. If you don't, bad GPU. If you do, bad RAM.
