    HD 5470: black screen - win 10



      I have a great problem with my HP G62 b26SL notebook.

      This pc has a Ati Hd 5470 (with 512 mb) vga.


      After the upgrade to win 10 the vga  is not recognized, so I removed the driver and I tried to install the vga driver by HP support (version for Win 7).


      Before install these drivers, I setted the compatibility with Win7 as this guide AMD Switchable Graphics not working in Windows 10 (HP Pavilion - Microsoft Community


      But During the installation , appears a blu screen and the pc restarted.  After the log in, I only can see a black screen and I can't do anything.


      Help me please

          while installing display driver issue with black screen crash and some time mouse is showing flickering .....

          i try many driver version not able install stuck or freezing..after only way hard shutdown

          then i try uninstall amd display driver on safe mode then it able to login normal with Basic display adapter.

          now unable to install any amd display driver for GPU it useless...

          i have no found any solution in forums .




          finally i find the fix for my laptop  Amd HD 7650M 2GB + i5 intel


          a.black screen issue when logon and b.installation black screen issue

          1st try with hdmi / vga connected second monitor then try to install  or try to turn on laptop still issue persists

          it a hardware failure gpu dead.try below step it worked for me.

          1. need "air heat gun" and "heat thermal paste".

          2. disassemble laptop fully.

          3.remove heat sink with fan from motherboard clean the fan dust if you have and now able to find chip process and AMD  Gpu in laptop.

          4.read the chip which one is GPU and take "air heat gun" blow up-to 5 to 10 min then wait to cool 30 min don't touch chip.

          5.put the thermal paste on both intel proccess + amd gpu chip place the heat sink carefully.and assemble your laptop

          6. turn on  install any catalyst driver .i have install 15.11 catalyst  (don't install crimson driver it burn your GPU)

          and enjoy

          it working fine for me...

          this very risk i have sony laptop the company is closed . i have no choice to service. i done by myself.

          it help someone keep try any dead gpu and black screen issue
