I had similar trouble installing latest Drivers. I had one of two issues. Normal Windows Boot then install - Screen would flicker at Driver install(As it has on past updates) but at third or fourth flicker screen would go blank and monitor would say no HDMI input detected(DVI-HDMI cord used for HD Monitor).
The second method would be a clean install after using the downloaded AMD cleanup, deleting temp files and shuttingoff firewall and anti-virus. This would force screen to lowest resolution and allow install. However, upon reboot, after windows splashs creen but before Windows Login, the screen would go black with a cursor in top left corner. No mouse and no keyboard inputs apparent. This would force a computer reset.
This may be helpful: I unplugged the crossfire ribbon from both graphics card and reinstalled using the second method above. This installed everything correctly. I then replugged in the crossfire ribbon to both graphics cards. However, crossfire is disabled in AMD Vision Engine Control Center. If you attempt to enable crossfire there, the screen will flicker and go black with cursor in top left corner of the screen.
I am not sure how much it will affect everyone's performance to run their computers with crossfire disabled and latest drivers as opposed to reverting to an older driver (Catalyst 12.10 as Marc@AMD mentioed). I just thought the additional info about installing with the crossfire ribbon detached might be helpful.
I hope that the next driver update from AMD will have this resolved as I would hate to think my investment in two expensive video cards is going to waste. Especially since many games and such do not function as well with the older video drivers.
