I was having issues with my computer not performing as it should and after trying everything I could think of, I did a fresh install of windows. During the installation of the graphics driver, my pc crashed and it just stays at a blank black screen when I try to boot it back up. I've reinstalled windows about 5 times so far with the same results. I was thinking it's either my psu or gpu. I have a Corsair cx600 and a Gigabyte gtx 760
