The Blue Screen of Death is a nightmare for Windows users, and no one wants to encounter it. Microsoft has been trying its best to rectify errors by providing regular updates, but there are still many issues causing Windows to crash.

atikmdag.sys error

Many people have reported a Windows 10 BSOD error caused by atikmdag.sys while upgrading from Windows 7 or Windows 8 to the latest build, i.e., Windows 10. This blue screen of death doesn’t allow the PC to boot normally. Restarting the PC also doesn’t work in this case, and this error persists.

1. Manual Solutions to Fix BSOD Error atikmdag.sys

The solution to fixing the BSOD error caused by atikmdag.sys is quite straightforward. You must uninstall the conflicting drivers from your PC. Follow the instructions below to resolve this error.

1. Boot the PC in Safe Mode by pressing the F8 key multiple times during startup. This will take you to a menu where you can choose an option. Click on Troubleshoot, followed by Advanced Options.

On the next screen, you will see Startup Settings. Click on it and press F4 or F5 from the screen appearing thereafter. Your PC will restart and enter Safe Mode.

atikmdag.sys error2

If F8 doesn’t work for Safe Mode, check out the guide on how to start Windows 8/10 in safe mode. Once it has booted into safe mode, return to this guide.

2. Now, you will need to remove the drivers causing the trouble. For the purpose of uninstalling the drivers, navigate to Device Manager by pressing Win + X and selecting Device Manager from the list. Find the conflicting driver and right-click on it to uninstall it from the system.

3. After uninstalling, navigate to Programs and Features within the Control Panel and remove AMD Catalyst Install Manager (for AMD graphic cards) or any other software associated with your graphics card, the same way you would uninstall any other application. Reboot the computer after this process.

4. After rebooting, download and install the latest drivers; your issue will be resolved.

hi kevin
i tried your solution didtnt work
i have ATI radeon mobility 5470 switchable GPU and Intel hd GPU
windows 10 64bit
laptop HP G62 a53se

Can you go to Control Panel and Uninstall all ATI related programs; and the Display Adapter. Then reboot the PC so it can pick the default generic driver. Once done, see if the error comes up? You should not be getting the same graphics as you were but to diagnose this, we need to do this. Once done, let me know so i can provide the next steps to bring the original driver back.

Omar Al-obaedy Oct 31, 2015

done it.let windows update find my driver installed it restart but unfortunately same thing.i have tried a lot of methods bu didint work
please help.

K. Arrows Author Oct 31, 2015

Are you getting the atikmdag.sys error or something else? Can you paste me the exact error.

am getting this VIDEO_TDR_FAILURE(atikmpag.sys)

Disable windows from automatically updating here: see here https://support.microsoft.com/en-us/kb/3073930 ; then uninstall the ATI Driver and let it run on Intel HD and see if it stills reports the error.

its working fine on intel HD crad,whenever i install amd driver it crashes.

I know that. Did you disable the driver update?

ok now i did whats next?

Now please download and run this; and tell me if that fixes it?

http://support.amd.com/en-us/download/desktop?os=Windows+10+-+64

let me give it a try and will report back.
thanks in advance

hey.installed it but this error happened?

Right click on it; and uninstall it. Then reboot and test.

do u mean without install it again?only on intel right?

K. Arrows Author Nov 1, 2015

Yes. I want to see if it automatically installs it.

Omar Al-obaedy Nov 1, 2015

does not install it automatically

K. Arrows Author Nov 2, 2015

So to summarize this; when you manually installs it returns that error?

Omar Al-obaedy Nov 2, 2015

exactly,my laptop become very slow and THE error appears

as i new from hp that this kind of laptops has two GPUs Intel and ATI and ati driver is for both of them

Hi Kevin, I tried your solution with uninstalling ATI driver as in Omar’s case. But it automatically reinstalled it even after turning off windows update. With a series of continuous restarts, I had to reset the system to initial windows 10. Now there’s a permanent display problem – there are 3 pairs of vertical lines across the desktop screen. only safe mode opens up with very limited options available. Your suggestions at this point?

K. Arrows Author Dec 30, 2015

I would suggest that you submit this as a new question on equestions.net/ask so i can assist directly.

Dj Nino Feb 19, 2016

Thank you very much Kevin . You ‘ve been a big help. 2 weeks I bother to solve this problem. every time you open a browser , I get a blue screen. Thank you

Hi there,
So I managed to get to step three however I don’t get an option to uninstall when in programs and features, when I attempt to change the install manager I get an alert telling me that Windows Installer service isn’t available in safe mode.
Not sure where to go from here, or if this thread is still open.
Thanks for any tips in advance

K. Arrows Author Aug 13, 2016

Can you boot into normal mode and then see if you’re able to uninstall?

just tried that and it crashed before i could attempt

though it did actually boot up so i’m attempting again

Did you disable the driver signatures before booting into normal mode?
If it can’t uninstall the driver in Safe Mode, try rolling back to a previous version.

okay I got the install manager uninstalled in normal mode, just downloading new drivers now, thanks for the help

welcome.

Welcome

I tried this and I got to the point where I restart in safe mode however it tells me my password is incorrect even though I know for a fact it is. I can’t get into my computer 🙁

Are you able to login to the normal mode?

b.link Aug 15, 2016

I use personally pin code for log in, when starting in safe mode I had to login with e-mail password instead of pin

How do you know which driver is conflicting?

atikmdag.sys is the display driver.

Jocelynang Baliwag Aug 15, 2016

Hi goodevening Ive tried system restore and it works perfectly thanks 🙂

Thank you, worked perfectly! Only thing that struggled was pressing f8 while rebooting, I restarted while pressing shift as workaround.

Lorenzo de Virgilio Oct 26, 2016

Hi, I did all the steps and keeps on giving the same problem and I have no clue how to deal with it

K. Arrows Author Oct 30, 2016

Follow steps from here: https://appuals.com/video_tdr_failure-atikmpag-sys-windows-8-110/ using the DDU utility in Safe Mode to uninstall the driver and then reinstall it.

Mark Moore Oct 21, 2017

When I’m in the device manager should I be seeing “atikmpag.sys” as a display adapter? I only see one option – “ATI Radeon HD 4200” under display adapter. Should I uninstall this “ATI Radeon HD 4200”?

K. Arrows Author Nov 18, 2017

No, you should not be seeing atikmpag.sys, that’s just the file name. Yes, please uninstall and reinstall the latest driver.

Jon May 15, 2020

Can you share the driver for HD4200 if possible as I upgraded to windows 10 and my graphic drivers are not working.
