Looking for help with this error: "system_thread_exception_not_handled atikmdag.sys"

[5to82allday]

First off, I have Windows 8.1 and a Radeon HD 7870 GPU

I've gotten the BSOD twice so far with this message displayed. The first time was a few days ago, and now it just happened for a second time moments ago. I searched it on Google, and most links lead to it being a GPU driver issue. Even got a search result from this very website saying the same. But I went into Device Manager and checked the driver on my GPU, and it's already updated to the latest driver. So now I'm trying to figure out what the problem is and I'd love and appreciate any and all advice.

Uninstall all drivers related to GPU and clean the registry entries too, this software can help you to do the job :

After that download the latest drivers(not Beta) from AMD's site and install it. See what happens.

Thank you for the advice. How do I select just GPU registries to clean?

And when you say uninstall all GPU related drivers, would it be enough to go into Device Manager > Display Adapters > Radeon HD 7800 Series > Driver and uninstall from there?

Download the software I linked you above, it will do the job for you, meaning it will uninstall the GPU drivers and will clean the registry entries too.

Download then install the software, then run it.

You will see Tools tab on the left, click on it, find the GPU drivers, click on it to highlight it, then click the button "Run Uninstaller" top right hand side.

This will clean the drivers. Then on the left hand side you will find a button "Registry" click on it, then click "Scan for Issues", after the scan is complete
the button "Fix selected issues" will become active, click on it, first select NO to the resulting window, then click "Fix selected issues" that's all.
