Ok guys I am having a computer graphics card issue. This is not a new computer and everything was working fine before hand. My graphics card is a gtx 780. Today I saw there was a new driver update so I did what I always do and installed it. Well while it was doing its thing I know the screen goes black and comes back maybe a couple times. Well now it went black and it never came back on. And the monitor just flashes this grey color. I really need some help here guys. I do not know what to do. I'm freaking out because I have a lot of important documents on here that I can not lose. So any help would be appreciated. Oh and my mother board is a Asus maximum hero I beleieve. Thanks guys
