So i recently upgraded to windows 10 and then upgraded my graphics card driver and then my computer completely crashes. I have reinstalled windows 8.1 but each time i install my graphics card driver my display gets pixelated then crashed i can reboot in safe mode. But i have to disable to driver in order for computer to work. i can not upgrade to windows 10 either without it crashing. Please help me in figuring out how to fix my computer to get my graphics card working again.
