Hi everyone, I have an alienware m17x with an AMD radeon HD 7970m and running windows 8. My computer was running badly during games so I tried to update the drivers for my 7970m. I first unistalled catalyst control center then uninstalled the drivers, then I began to install the mobility radeon driver verification tool. It begin installing the driver then my screen went black and flashes on and off. Don't know very much about computers so any help would be appreciated.
