So I've just installed a graphics card(AMD Radeon HD 7850)and after I did so the screen is all glitchy and it turns off into a black screen after a few minutes of use, I suspect it is because I don't have the driver installed but every time I try to install the driver it shuts down before I can download it. I'm hopping there is some way for me to get the driver on there without downloading it, however I have not found it. Thank you for reading this and hopefully helping my situation
