I have AMD Mobility Radeon HD 5470 graphic card installed in HP G62 laptop. Laptop came with windows 7 with everything working.
Last year I updated windows 7 to windows 8.1 with that I also updated all my drivers including AMD driver. I installed version 14.4 from AMD website. It all worked fine after that.
Few days ago I started facing some graphic problems like distorted pixels on the screen and after that laptop rebooted itself. It used to happen when I was watching video or playing a video game. After few days their number of occurrences increased as it became impossible for me to do any work.
Then I decided to update driver. I downloaded latest version of driver that is 14.12. When I installed that, between the installation laptop restarts and it booted into blank logon screen.
Somehow then I started safe mode and from device manager I updated the AMD card driver to Microsoft Basic Display Adapter. After that I was able to boot into the pc in normal mode but when I open device manager there is a yellow sign on Microsoft Basic Display Adapter. When I try to update the driver it again goes to blank screen on startup then again I need to change it to Microsoft Basic Display Adapter from safe mode. I have also seen blue screen for several times of error like, SYSTEM_THREAD_EXCEPTION_NOT_HANDLED and VIDEO_DRIVER_INIT_FAILURE.
I have also tried installing that 14.4 AMD driver software. It installs successfully but nothing changes.
On HP website there is only one AMD driver which is for windows 7. I also tried to install it but find no luck.
I hope someone can help me in fixing this problem.
Thanks in advance.
