Windows 10: Occasional BSODs caused by atikmdag.sys

Great to hear!

Happy to help *Smile

 

Hey there, I occasionally get a BSOD which happens fairly randomly, can happen a couple of times a day or once every few days. The error I get is SYSTEM_THREAD_EXCEPTION_NOT_HANDLED caused by atikmdag.exe

I have used the AMD Clean Uninstall utility to reinstall my graphics card drivers, updated my Windows and all that, but still get the BSODs.

BSOD - atikmdag.sys & Crtitical Structure Error

I installed Win10. I installed a game which kept causing a BSOD with atikmdag.sys. I fixed the issue by copying the atikmdag.sys DLL from ATI to System32 drivers folder. The game launched after that.

However, now the computer keeps crashing with Critical Structure Error BSOD, and the solutions for them suggests upgrading driver for ATI which again takes me back to the first issue.

 

Driver IRQL Not Less Or Equal

I finally had a BSOD with a message pointing to ATIKMDAG.SYS as the reason for the BSOD. I was able to locate a bundle of drivers from HP and extracted a new ATIKMDAG.SYS and installed it on my system. I have been stable ever since.

GPU TEST


Run Furmark tutorial



Note Run Furmark for around 30 minutes



Warning Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them and abort the test if temperatures rise too high
When finished, make a photo/screenshot of Furmark and post it.

In Furmark you can find a tool called 'GPU-Z' (if you want to install GPU-Z is up to you), when GPU-Z is open click on the 'Sensors' tab, on this tab you can monitor

• the frequency of the GPU,
• the GPU memory clock,
• the temperature,
• the power,
• the load on the GPU,
• Etc.

I would like you to make a screenshot of GPU-Z after you have either cancelled Furmark for any reason or Furmark is finished, post this screenshot in your next reply with the result of Furmark.

 

I ran the Furmark for 30 minutes but the screenshot didn't save to the folder, so I just ran it again until it stabilised at what it was before: Screenshot

Here's the GPU-Z sensor screenshot whilst it was running: http://gpuz.techpowerup.com/18/04/09/636.png
And the actual graphics card stuff: http://gpuz.techpowerup.com/18/04/09/mrq.png

 

Have you reinstalled the same drivers or have you installed different drivers?

 

I reinstalled the same drivers as I wasn't sure what driver version I wasn't getting these BSODs on.

 

Could you try an older driver, or newer driver instead of the same.

 

I clean installed the latest drivers, and just had a couple of BSODs with the same error.

 

Please do the following 2 things:

• Reseat or seat the GPU in a different slot
• Run a memory test

Diagnostic Test

RAM TEST


Run MemTest86+ - Test RAM - Windows 10 Forums



Note



MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

 

I have reseated my graphics card + RAM, whilst I was at it I thoroughly cleaned my graphics card heat sink as it was incredibly dusty. If I get another BSOD today I will run MemTest whilst I am asleep, although hopefully it was the graphics card that was the problem.

Thanks for the help!
