How do I know If my ATI Raedon display adapter has gone bad?

1

I have ATI Mobility Raedon HD 5470 in my sony vaio laptop and it was running with old driver. My laptop was little bit slow so I decided to install the latest version of that and I went to ATI Catalyst Auto detect page downloaded the latest one and installed. After installation it detected the display driver as ATI Mobility Raedon HD 5000 Series. After that it shows something Graphics driver stopped working.

After that I was unable to start most of programs (like VLC Player, Photoshop,). When I start it Crashes and shows stopped working so I uninstalled the latest version and re-installed the old version successfully. but the problem still persists.

If I disable the display adapter from device manager then everything works fine but display looks very bad and I can't control brightness. What should I do now?

Your experience is common with ATI drivers. The original driver had nothing to do with your laptop being slow. The built-in video uses an ATI chipset but it is not necessarily identical to a retail product. The computer manufacturer (Sony in your case), provided an OEM driver designed for what is inside your computer. ATI periodically offers updated drivers, but these frequently do not work with OEM hardware. I'm only guessing that remnants of the new driver remained when you tried to reinstall the old one. When you disabled it through the device manager, the computer was running with some basic video drivers, which is why it looked bad.

The only place to get drivers for the OEM hardware is from the computer manufacturer (unless you can't). Here is a Link to Sony's download page. You will need to find your particular laptop, which you didn't identify in the question. Download the latest driver (don't be surprised if it hasn't changed from the original; there is rarely a need to change the original drivers).

Re-enable the display adapter in the device manager. Completely remove the ATI drivers following the instructions here from the AMD web site. Although it isn't mentioned in those instructions, you may need to do the uninstall in safe mode. Then install the driver downloaded from Sony.

If the problem remains, it is likely that all of the remnants of the new driver were not removed. There are a number of third party removers. AMD used to have a separate removal program. Some online discussion indicates that it may still be available, buried on the ATI driver downloads page. From the comments, I understand that you tried the one covered here successfully, running it in safe mode.

Did you remover the old driver according to the instructions at the AMD link? – fixer1234 – 2014-10-08T05:46:45.500

Yes dear I uninstalled that way, restarted, used CCleaner after that re-installed. – A. Prasad – 2014-10-08T05:57:02.077

This link: http://www.sevenforums.com/graphic-cards/224739-how-completely-remove-amd-ati-applications.html is a few years old but you might find the discussion useful. AMD used to have a separate removal tool that cleaned up all of the remnants but I'm not finding current links to it. There are a number of third party programs but I'm not familiar with them, for example: http://forums.guru3d.com/showthread.php?t=379505. It might be worth contacting AMD customer support.

Thanks for getting back with the solution that worked for you. It's always good to get validation for a tool I haven't personally tried. Glad you got the problem solved. I added the information to the answer. – fixer1234 – 2014-10-08T12:04:01.920
