Normally when it goes black while installing, it's cause it's installing the graphics driver, it should cut your screen back on after a couple of minutes. If not, tell me which driver from AMD were you installing? Auto detect? Beta?http://support.amd.com/en-us/kb-articles/Pages/AMDCatalyst13-11APUBetaDriver.aspx
That's the beta Catalyst 13-11. See if that one works. If not, you might have to sift through some old Catalyst drivers to see which one works for you.
