Radeon 6650M problems Win7

[vyanor]

Hello everyone!


This is my first Forum post because so far i could solve all problems by answers I found on other posts.. so don't be too harsh if there is a solution for my issue because i didn't find it


Okay... my problem is, that for some time already my build in AMD card has stopped working.

Now after some playing around I see the card in the device manager and in speccy, but I still can't use it.
Furthermore i have been to this stage already and was even able to use the card, but as soon as i started e.g. Skyrim using the AMD card the system shut down after a few seconds.

So I tried deinstalling the driver and starting again, now with (i think) the same driver installed again, I can't even select the AMD card for Skyrim anymore.
Also i get a system freeze (like 1 minute) every time after booting, without error message or similar.
I tried several (like 10) driver installations, different settings, etc.

Crawled through really a lot of posts i found on google and tried many different solutions but nothing seems to work for me.



Current installed driver (from manufacturer page) is: amd-catalyst-15.7.1-with-dotnet45-win7-64bit

It's a Lenovo G770 Laptop and i didn't use it too frequently but i remember some 2 years ago it was set up with win7 as well and was working fine.

Here is a snip from my Speccy results to give a general overview of my system.

So.. i hope someone can help me with this problem to get it running again or at least to get to know if its broken or whatever is wrong
I still hope this can be fixed, even though i try it since about half a year from time to time.

If there is any information missing please tell me and i will include it as soon as possible.


Best regards

Hi,

Please do try these troubleshooting steps that may resolve that issue.

- Go to Device Manager and right click on the AMD graphics driver and select uninstall.
- Do the same in Programs and Feature, uninstall anything related to AMD.
- Download and install the latest driver from AMD support site.
- Here's the link: http://support.amd.com/en-us/download
- Once installed reboot your laptop and observe it again but that should resolve the issue

Thanks for the answer but it didn't help. That was exactly the driver i had installed. I tried to remove everything and reinstall it but it didnt bring a change. I still can't access the card.
Is there any program, cmd command or something else where i could check if the card is actually working or if its broken?

(It is visible in device manager and speccy)

Further information:


In FurMark GPU stresstest software it shows me GPU 1 as the integrated Intel card and GPU 2-4 as "not available".
*But* if I open GPU-Z it shows me all details like temperature etc about my AMD dedicated card.. how comes that oO
I'm really not getting any smarter on that issue...

Well with a lot of trying and tweaking it seems to work for now, i can't provide a "solution" though..
