I have a hp pavillion dv7-4069wm laptop. Windows 7 64-bit, AMD Phenom II N830 triple core 2.1GHz CPU (8Gb RAM), Mobility Radeon HD 5470 DDR3 (512Mb VRAM) DX11 GPU, System board 1443 67.33, System BIOS F.28
I have successfully installed every catalyst update for the past 2 years as they are released thru catalyst 12.4. Catalyst 12.6 & 12.8 successfully installs for me, but after it is finished & I reboot Windows notifies me that there is no display driver available. Catalyst 12.6 & 12.8 will not boot up. I have tried uninstalling in programs & express uninstall from the AMD Install Manager before attempting a reinstall. For some reason the Install Manager will not uninstall from programs in Windows. All Windows will do is attempt to repair the AMD Install Manager. I like to keep my drivers up to date because I buy new games frequently. The notes for the Mobility Radeon Catalyst 12.6 & 12.8 pages both show my GPU is supported, but I have had no luck with them at all. Does anyone know if there are any known fixes for this issue I am having with my 5470? This is my 3rd month without being able to update my GPU, & I am starting to get agrivated by the lack of support or response from AMD. I have reported this issue to AMD several times with very detailed info for them, but I have recieved 0 replies. Now I am trying to find help here. Anyone?
