Purpose of this article

This error has been a constant problem on my new PC for the last 8 months. This particular error exists on both ATI and Nvidia cards and on a whole range of different PC builds.

The error you receive on the cards is different because obviously the driver that stops has a different name, but the symptom is the same, the screen will go blank and then sometimes the game/application will recover or it may crash. A small message will appear on the bottom right hand side of your screen if you are using Vista.

ATI Cards: Atikmdag has stopped responding and has successfully recovered

Nvidia Cards: nvlddmkm has stopped responding and has successfully recovered

This page contains all the information I have collected and possible fixes and puts them in one place.

This page will be constantly updated until a 100% Fix is found - the fixes that are listed work for some but not for others - so you might have to experiment a little until a solution is found

I will point Nvidia users to the best solutions for them and then list possible fixes for ATI users - I am a ATI card user myself and have found a few fixes which increase the stability of my system - this has reduced the frequency of the error but has not eliminated it entirely.

Fix 1 - Vista Users - ATI and Nvidia Users

Windows Hot fixes

Some users have solved the problem by actually uninstalling a windows hot fix, the "KB952287" patch. (Vista Users)

I had this problem and found it quite annoying. Due to other circumstances, I reinstalled Windows Vista, and found that I did not have this problem before installing updates. In fact, installing update KB952287 caused this problem to start, and when I un-installed this update, it went away.

I looked up the update, and it deals with some very specific SQL server issues that I will likely never deal with, so it will stay gone on my machine.

Thank you Matthew from Utah!
Your solution worked for me.

I un-installed "update KB952287" and the problem is gone.

I also use the AMD 780G chip set.

Possible Helpful Patches

You may have these fixes installed already, write them down then check if you have them installed.

Fix 2 - Only using one stick of Ram - All Users

According to several posts I have read over the internet a sure-fire way to rid yourself of this problem is to only have one stick of ram in your PC. I personally have not tried this method as I only have 2gb of ram, reducing it to 1gb would not be enough for me as I am using Vista and have to run several applications.

quote from ocforums:

'Drivers, software, vista driver structure and sub-level timings, etc...simplest way to get rid of the problem is to run one single RAM stick...I kid u not. 1 ram stick and u will see the issue vanish almost instantly!'

If you are so sick of this problem and can reduce your PC to only one stick of ram then give it a go.

*Warning* Only remove ram if you know what you are doing - you can quite easily damage your components if you are not use to repairing computers.

Fix 3 - ATI users XP and Vista - Total Fix of the atikmdag error on my System

*Warning* You do all of this at your own risk - I am not responsible if anything goes wrong

Update 30.9.2007: I managed to totally remove my atikmdag error now following the information below

My PC Build:


Tools you need:

Stage 1

  1. Disable UAC - Vista Users (see below) - reboot
  2. Disable any Antivirus software
  3. Remove Current drivers
  4. Reboot into safe mode - to do this you wait until after the bios screen has disappeared (bios is the start-up screen) then tap the F8 key until the windows booting options come up - select safe mode
  5. Run Driver cleaner - select the following options below and then click start
    Driver cleaner
  6. Empty your recycle bin
  7. Reboot into normal mode
  8. Install Catalyst 7.9
  9. Turn Antivirus and UAC back on
  10. Reboot your PC


Stage 2

This stage is what removed the error for me. My ATI card is a HIS Ice3q 1950 Pro which is an overclocked video card. Doing some research I found that it wasn't very stable running at the speeds it is set at, so I made one small change to the VPU clock speed. Obviously I don't know what card you have and weather this will make any difference for you, but I can say that before most games had this error every 5 minutes of game play and after I haven't had the error since.

On the ATI tool main menu you will have your graphics card clock speeds. My core speed was 621 I reduced this to 600 and pressed set clock - the tool set it to 594 - I saved the profile and that was it - that little adjustment removed the error. Your graphics card will run at different speeds to mine, but it might be worth dropping the core speed by 20 points to test if this works - also make sure you go to stage 3 as well.

vpu clock before VPU Clock after

Stage 3

I'm hoping the above has also fixed your error - if it has or hasn't leave a comment at the bottom of this page.

Fix 4 - Various methods that work for some - Vista Users

Reading through all the hundreds of posts I took down notes and kept a record of what worked for some people, some responded saying that it worked, some say it made no difference. So give some of these a try and see if it makes a change.

Turning off Aero: Start / control panel / under appearance and personalization / change the color scheme / Select Windows classic theme and apply.

Turning off UAC (User Account Control) - *Warning* UAC is designed to help keep your PC more secure - try this if nothing else works, turn it back on if it doesn't help.

Type msconfig into the search bar (pic below) - run the program

Select tools and scroll down to disable UAC and click launch (see pic) - reboot your PC

system config

Fix 5 - More Possible solutions to the atikmdag / nvlddmkm error

This is basically as far as it goes for now, but these are few other fixes that you could try:

Fixes from comments below:

Robb from Canada:

Had the same problem until I set my bios setting to auto! Now everything is good to go!

Steve from Australia:

If you are using EXTENDED DESKTOP WITH DUAL MONITORS then disable it and revert back to using one monitor.Ta Da! no more crashes!

Greg from UK:

I have got the system stable by uninstalling the ati driver and using the standard vista vga driver, aero and window transparency don't work, nor do any of the screen savers but no more BSOD..

Still Isn't Fixed? - if you still have problems or can offer a solution to the atikmdag or nvlddmkm error please post a comment below - Thanks!

I had this problem for years. It was finally gone when I changed my motherboard (as it failed). I had ASUS motherboard and replaced it with a less known manufacturer -> all problems solved.

Actually, at the moment the problem only disappears when I remove any (non-onboard) sound card (tried different cards, all "cause" the error when built in). Any ideas about that?

Hi Guys

I just read this on another website:

"The issue occurs when the Timeout Detection and Recovery (TDR) feature available in Windows Vista® and Windows 7 detects that the graphics card (GPU) has not responded within a predetermined period of time and reinitializes it with the Windows Display Driver Model (WDDM) to prevent the need to reboot. There is no single cause for a TDR event to be triggered."

There is no single cause, so it can be either software or hardware or a combination of both.......

Tried everything and no luck, then i found this site, tried most things on here but the thing that seems to work best is running my 4 core CPU on 2 cores. Vista x64 ultimate.

Luke, yor solusion is perfect.
Additional- laptop is more coldnes

I believe it is caused by the TDR delay (win 7 and vista), I found something about it on the microsoft website and after playing around found this works 95% of the time. It does still crash, but probably about once every few weeks instead of every 5 mins.

Win 7 users -- Start -> Run (if not there ctrl, alt, del -> taskmanager ->file -> run)

Type regedit press enter, then yes on the user account control pop up.

Using the left hand pane navigate to HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control GraphicsDrivers. The right side of the window should have two keys, default and something about a kernal.

Right click an empty space below these two files. Select New -> DWORD (32-bit) Value, Rename it TdrDelay (case sensitive), next right click it and select modify. Change the default value to 7 and click OK. Exit the regeditor and reboot.

-- Note, YOU MUST CHANGE THE DEFAULT VALUE; if you leave it at 0 it will constantly reset the graphics driver. Choose between 3-9. There is an option to change the data between hexadecimal and decimal. I dont know the difference. Mine is on hex and it works, so does the 2 or 3 other computer i done this on.

IF IT WORKS FOR YOU DO AS I HAVE DONE AND SPREAD THE WORD! The hard part is done just copy and paste.

Had this problem for about 6 months and had almost given up. Had done all the suggested fixes with the drivers but under clocking the GPU memory by onlu 50 sorted it.
Using windows 7 with asus HD6670

Just to comment removing 1 stick of ram will work if its bad RAM but you should be able to test that with memtest. Don't just run on 1 stick without checking.

Admin:  Glad to hear you solved the problem!

Had same problem when playing games like crysis 3, far cry 3. Tried many stuff except reformatting hard drive, nothing worked.

But one thing fixed this problem, it was related to directx11 and ati drivers (geometric instancing), I just put in game cfg file lines to turn off geometric instancing (r_GeomInstancing = 0) and problem went away for 5 days now, and had like 20 times a day.

Admin:  Thanks for sharing this information!

Windows vista business - had this problem for 2 months, incredibly frustrating.
Tried fix 1 - uninstall KB952287 - this didn't help for me.
Tried fix 5 - change theme to windows classic theme - this seems to have solved the problem.

Thanks so much for helping!!!!

Strange type of this problem. It appears only in Dolphin emulator. When I play pc games - its ok, no error.

But after some time of playing on Dolphin - black screen, videodriver has stopped, ets. I played on Dolphin before, on different revisions, on 32x and 64x kinds of Windows 7. But a while ago... There is this problem. There are no overheating, no overclocking, no errors of RAM in memtest.

I tried possibility all variants of solving this problem. I asked about it on official Dolphin's forum too, but there are no helpful answers. I hope on this place.

My spec. is:
Cpu AMD Athlon II X4 620 2,6 ghz
MB Asus M4A785TD-M EVO
RAM Samsung 6 GB pc3-10666 (1333 mhz)
VC Nvidia Geforce GT240 DDR5 512
PS Inwin EN-028 400 W

I have windows 7 64, I installed a new Radeon HD 7850 in September. It was working great up until November. In November I upgraded to windows 8 and within a day or 2 I started having hard lockups and once in awhile I'd get a display driver has stopped responding and has recovered error.

But mostly it would just hard lock. I took it to Compusa and they had it for 2 days running whatever 6 hour program they run that shows if there's a hardware problem and also updates any outdated drivers. I was told they never had it lock up during those 2 days.

But within 5 minutes of me having it back home it locked up. I took it back and this time just had them reinstall windows 7 64 again because I thought it was an issue with Windows 8 and the catalyst control center not being fully compatible.

Got it back the next day and within an hour the same issue with lockups and display driver has stopped responding occurred. I've been researching online and trying everything short of removing my Ram to see if it will solve my issue. Ram I have 12gb, but it consists of 6 sticks of 2gb. I just don't know how well my computer would run on only 2gb (if at all).

Now that I'm pretty sure these errors didn't have to do with upgrading to windows 8 I'm wondering if maybe one of the windows updates or catalyst control center updates in November caused this? I just don't know where to look since my computer has a fresh installation of Windows 7 64 as of 12/20.

Admin:  Hmm that does seem strange. I instantly thought it might be your power unit not be being able to handle your new graphics card, but you mentioned you have had your new card running for a while. Could you possibly reinstall a previous version of the catalyst control center?

Thanks for this page. Just want to throw in my 2 cents:

I have had this problem every 2-3 days, 50% of the time going to BSOD.

I am on Win 7, 64-bit, 6GB of RAM.

I have tried everything here and what seem to have finally worked for me was removing 1 specific stick of RAM.

I did run Memtest prior to physically removing the RAM but no problems was detected.

I had to find the faulty stick only only by trial and error.

Thus far, 2 weeks with no problems at at all. If I can reach 1 month with no problems, I may try replacing with the faulty stick to see if I can recreate the problem.

Will post again on my findings.

Good luck to all with this issue.

Admin:  Thanks Damien, I'm glad the problem has been solved for you, let's hope it stays that way!

Okay - here is what I've found out:

My problem was the hardware, not the software. As soon as I bought a new graphic card everything started working perfectly.

I guess it was the cooling system, which wasn't working accurately. Because of this the GPU got too hot -> it turns off.
I wasn't sure if I should buy a new cooling system, that's why I just bought a whole new graphic card. xP ...

Maybe you guys should check the cooling system of your graphic card, that MAY be the problem.

ATIKMDAG Is Annoying   Kent 

Tuesday, October 30th, 2012

I've had this atikmdag stopped responding error for a while now and it's really getting on my nerves “Big Time”

I have tried nearly all of the fixes mentioned in various articles on the web. It's obviously that a lot of people are experiencing the problem judging by the amount of people who have commented on this thread plus all the other forums and posts that mentioned this problem.

I have had the problem for about 2 months now, it's becoming quite predictable and seems to happen more with certain games.

Here is a list of things I have tried without success:

1. I deleted and then re-installed the New ATI Drivers
2. Performed a Memtest86 – that came out fine
3. Checked the voltage, amps and temperature of the graphics card, all are fine
4. I cleaned the registry, that made no difference
5. I even flashed the BIOS on the graphics card as well – no difference
6. I completely removed my operating system and reinstalled it
7. Upgraded Direct X – no difference

I am using Vista, I know its old but I am wondering if this problem is happening with other operating systems as well?

I'm thinking its hardware related, I will try a friends graphics card in the next few weeks to see if it makes any difference.

Same here - while playing Skyrim I got a pixel-party and afterwards I got a black screen + the classical message. I tried almost everything I found on the internet to get rid of it - nothing helped. (Athlon II x2, HD4890, 2 GB DDR2).

Then I used the system restore programme from Windows, to the point where I installed DirectX ... Even if I've deleted Skyrim (Rage-Mode) it seems to have worked, because I am able to run SWTOR without any issues.

Don't know how long it'll last ... so expect me to write again if it didn't worked out on the long-run.

I built my machine with high quality parts several years ago, and have been plagued by this problem ever since. Very disappointing. At first I thought it was from using Vista 64, but have since seen many others have the same problem. I have tried checking my memory, reg cleaning, driver changing, underclocking etc. Disabling or turning up TDR resulted in a complete system lockup. I have more or less given up. The problem only happens when gaming. The only thing I have not tried is either removing RAM or removing a GPU and why should I have to cripple my system to get it to work? If I knew if was a bad mobo/gpu/ram/OS I would replace the component but I am not buying new components when I am not certain it will fix this insidious problem. I will wait until this machine dies completely and then will buy a crapppy out of the box pc.

First of all, many thanks. Many thanks for the heros: the founders of this site :-) What a helpful site!

I was about to get used to having the "stop respond and recover" error followed by blue screen when opening so many internet explorer windows which contain videos. I stopped hardware acceleration from flash player settings and so far no more problems occured. Special thanks to ALEX, RAMON and www.repairyourpcnow.com

Hey guys, I posted earlier about a couple of fixes I tried that did seem to temporarily fix the problem, unfortunately it returned a short while afterwards, but I think Ive found a permanent solution.

When only using one stick of RAM in the computer I didnt experience this problem at all, this made it quite obvious that my problem was being caused by the RAM, even though memtest showed no faults in either module. I simply bought new RAM and havent experienced this problem in a long time.

If using only one stick of RAM fixes this problem for you, then I think its fair to say that the problem can be fixed by replacing your RAM

Good luck!

Admin:  Yep thanks. This problem can definitely be related to hardware issues. In my case it was the graphics card at fault. Underclocking the card solved the problem, but after a month or so the graphics card totally failed.

Games Like WoW will run but Runescape won't?

Getting the Atk error message 15 seconds into game and it drops. Not sure where to find my program to underclock speed? any help is apreciated

E   London 

Thursday, February 2nd, 2012

Not sure exactly which of these worked for me, and I don't want to get my hopes up too high as it has only been a couple of hours without the problem (although it was happening every 10 minutes before), but here's what I did:


Did sc2fan's advice of clearing the registry using ccleaner (thanks for that), turned out there was 155 ATI-related registry problems, fixed them all using ccleaner. (this fix was the first one I did and it was done quite a while before the others and I experienced no crashes, so this could be the one that really fixed it for me)

I under-clocked my GPU core clock by around 20 Mhz as advised by many people here

This was posted by someone called yellowblood on a youtube video relating to this problem:

"In the control panel, go to "Power Options", "Change plan settings", "Change advanced...", and look for "PCI Express" - "Link State Power Management".

Make sure that it's set to "Off". This will cause Windows 7 to avoid trying to save power by providing less voltage to the GPU, which may be the reason for the crash."

Seems like it could be quite helpful to those who've tried everything else, this is probably the most inconsistent, random, and stressful PC problem I've ever come across, some fixes point to Hardware, Drivers, Registry, even only having one stick of RAM in the motherboard rather than two, it seems this problem has many ca** and trail and error is the only way to fix it. Here's to hoping the problem doesn't come back!

Good luck people

I mainly had the random freeze problem which appeared just 2 months after I bought my laptop (3 yrs ago). I experienced driver not responding only playing Sins of a Solar Empire.

Unfortunately none of the proposed solutions worked for me.
Three monts ago I formatted and restored all to factory settings (RTM OS included), now everything works again.

2 brand new PC's I built last year have been rendered useless by this problem. Both PC's have different components, this error seems to have no consistency, the only consistent factor is that both computers are running Windows 7! Microsoft should be providing their customers with a solution. I have literally tried everything, new graphics cards, up to date drivers, old drivers, RAM, etc.

The 2 temporary workarounds I found were these...

1) Uninstall ATI drivers and Catalyst Control Center. This will force Windows to use the standard graphics drivers. The screen resolution wont be amazing, but it will enable you to use your pc. This work around wasn't ideal for me as I do a lot of design work and need a good resolution on my screen. But it did stop the atikmdag error.

2) If you are using a multi-core processor, set Windows to single core following these steps..

Control Panel ---> System & Security ---> Administrative Tools ---> System Configuration --->

This will open a box with 5 tabs. Select the Boot tab, and then click 'Advanced Options'

Click 'Number Of Processors' and select 1 from the drop down menu. Then click ok.

I will add, to revert back to multi cores you will need to go through the same process, and on the 'number of processors screen' untick the box, click ok and restart your computer. The reason for this is if the 'number of processors' box is unchecked this forces Windows to revert to using all available processors on start-up.

Again this work around isnt ideal. Running in single processor mode can be a pain especially for someone like me who needs to run large graphic design and daw applications. But for everyday use like browsing etc it is acceptable.

Hope these help someone. I have repeatedly emailed Microsoft complaining about their poor response to this issue.
If you would also like to complain this is the email I have been using - directx@microsoft.com

Admin:  I know its crazy, this article is 4 years old now and still many people are having this problem! Anyway thanks for your input.

I have an ATI Radeon 5770. Since I bought my card I have experienced the Display driver amdkmdap stopped responding but has recovered issue and in Windows and also while playing Starcraft2. This issue also caused Dragon Age origins to crash CONSTANTLY.

My fix was to clean my registry. CCleaner actually found some old Starcraft 2 registry and ATI video card entries, which were removed. I played Starcraft 2 for 30 minutes last night and today for another 30 minutes.

Also I want to note that I tested a Nvidia GTX560 as well and the Display driver amdkmdap stopped responding but has recovered also occurred in Windows 7 professional 64 bit.

I really hope cleaning the registry fixes this issue for you too!

My DELL V3450 with AMD Radeon HD 6630M crashes with BSOD 0x116 anytime gaming. I'd tried to do many things to fix this error, such as:
> Update driver
> Install different versions of windows
> Check my RAM, HDD
> Disable hardware acceleration
> Disable Aero
> Change from 4 to 2 cores
> Underclock GPU

but nothing worked untill I saw your solution. It seems stable for a long time playing games. I'll follow it if there'll be any more crash.

I have a HP p6792uk Desktop that keep crashing whenever I tried to change the settings of the Microsoft Lifecam software.

I fixed the problem by uninstalling ALL the Catalyst program *using Add/remove and selecting "express" uninstall. Then I reinstall the drivers from the manufacturer (OEM, in this case HP) website. The I went to the ATI Website and did an update but did not opt for the AMD Vision Control Center (using the ATI Control Center of the HP original update).

I use Windows 7 32 and in my case I have both an ATI and an Nvidia card totalling 6 monitors.

I would get the BSOD often with error 116 and the same driver mentioned. Eventually what fixed my problem was to use the nvidia beta drivers and uninstalled all panels (ATI and Nvidia) and use only the drivers.

Then once I disabled Aero by using the classic theme, it all became insanely stable.

After two years I formated my HD and installed Windows Vista SP2 again. I just installed 3d softwares for my work and no games.

Two weeks and no more red dots, white horizontal lines or bluescreen caused for Atikmdag.sys or Atikmpag.sys.

When I used Firefox I installed flashplayer 11 from Adobe and some hours later ... Bluescreen caused for dxgkrnl.sys and atikmpag.sys!

What I did? Disabled the Adobe Flash Player hardware acceleration and no more bluescreen! :)

Of course... I installed my PC games and until now all work fine!

I am using:

After more than 10 hours of trying to fix that c***, I downloaded MSI Afterburner, clocked my GPU down for 10% and it seems to work, l0l00ll0l0l0l0l00ll0.

Hello World,
I am an IT Professional and enthusiastic gamer. 15 years in the job. Experienced and also desperate due to this issue.

I encountered the TDR issue 4 times with 3 different system configurations, triggered by at least 4 different ca** and solved by 4 different actions.

My current system:
AMD Phenom II BE@3.4 Ghz, 4GB Mushkin DDR3@1333MHz, ASUS Crosshair Formula 3, Sapphire Radeon 6950/2GB Dirt Edition, PSU Enermax ProModu 550W, all hardware running with default settings, Windows 7 Professional 64bit / Ubuntu Linux 11.04 64 bit, entire system and drivers are up to date

1.Configuration / Issue (occured 2-3 years ago):
Windows Vista Premium 32 bit, all available updates and service packs installed, all drivers up to date, no OC. Bought a new NVIDIA GF9800GTX ExoEdition. No problems at all, while working with standard applications (Mozilla, Office), but massive problems when operating at large workloads. Solution: Built in a new PSU 550W and happy, until ...

2.Configuration / Worst Issue (occured 1.5 years ago):
Upgraded to Windows 7 64bit in the meantime. System became very unstable, BSOD and TDR issue occured permanently and randomly. It took me weeks to solve. Although memtest reports no errors I decided to swap the RAM as long as it was in warranty. Problem solved, but ...

3.Configuration / Issue (occured 6 months ago):
Deja vu? Screen becomes blank, then reappearing with a message so familiar to me: "The display driver has stopped working ... nvkrnl.dll ... and has recovered ... and so on". Noticed also some flickering green dots on the screen. To keep it short: There were some or more cold solder joints on the graphics adapter's PCB.

I considered the oven trick (always worth a try) considered the ROHS compliance (lead-free soldering) in my plan and set it to 220° C, (duh! damn metric system! that's 428°F) after dismantling the fans, cooler and plastic parts, and resoldered the joints while leaving the PCB in for 10 mins in the pre-heated oven. Great trick, isn't it? But unfortunately this didn't work for me, so ...

4.Configuration / issue (occured less than 2 months ago):
I bought a new graphics adapter. This time it should be something completely different. Powerful. Reliable. Future proof. The Sapphire Radeon 6950 Dirt Edition with 2GB VideoRAM. After decades of using Nvidia in true conviction. Yeeeeeeessss, Sir!! I assume you will already know what happened next...

No problems while gaming, great performance, but severe problems when idle or when simply surfing the web or writing emails. "The display driver has stopped working, the warp core will be ejected, all personnel evacuate immediately." OK. This time it was software related. I tried the same with Ubuntu Linux using the proprietary driver and no problem occured.

If you are unsure if this problem is hardware related or not, I recommend you should do the same. There is even no need to install Ubuntu, you may simply boot from a Live CD and btw, you might even like it ...
The next thing you should do is to boot into Windows, check if your driver and additional software is up to date, enter AMD VISION Engine Control Center --> Performance --> Graphics Overdrive and disable all AMD Overdrive features available, apply and reboot.

This solved my problem so far, I have no loss of performance, and I hope this works in the same way for you, and also for me in the future.

My conclusion:

It's very, very hard to determine whatever may cause this issue. I'm afraid this will persist, as long as Microsoft will develope another more precise error reporting and response to certain different hardware and software issues.

Especially the 4th case might be a problem of dynamic over/underclocking (a.k.a. switching between High Performance and Energy Saving Mode), causing the driver not to respond in a predefined time. If this is the case, you can try to increase the tdr_value in registry to match your requirements, or simply disable this feature like described above.

If you are in doubt what hardware you should use to circumvent such problems, I would point to Nvidia. The software is mature and works like expected. But thats my opinion only. Decide yourself.

However, finally I would like to thank the administrator for taking care of this nasty problem and also for keeping this thread alive. At least, it felt good to experience, not to be the only one with such problems.

Admin:  Excellent, thanks for the detailed response, I am sure this will help others with this problem, thanks again!

Another friend found this solution and work fine to his Windows Vista:

Use a registry clean software and install **AMD Catalyst 11.1** Last updated 1/26/2011. AMD display drive version 8.812. Disable Catalyst A.I.

I used Catalyst 11.1 and did updates from Microsoft to my Windows Vista X64 and... work! Three days playing pc games and no more crash.

Well it seems we are zeroing out on the problem in the last few posts... to me it seems something about 4 cores machines using intensive programs and to games(not all games), so it got to be related to incompatibility with 4 Cores processors and code (Direct X myb?).

My problem is only related to gaming, I've done anything you can think of, including running M.R.I (Geek Squad Tools) performed an overall system faulty hardware test for 24hrs.. NOTHING!.. everything is ok!.

Some retail software code or Windows is interrupting the videocard rendering process, but it's not Memory, overheating, faulty hardware or corrupted drivers so what gives?...

The only solution that I've found is lowering the cores to 2 cores from 4 (like others above me did) but with 2 cores performance is not smooth at all.

PS: I don't crash when idle or with Aero on, only when gaming!.. also, I don't have the windows update mentioned here nor do I have overheating problems (i Know, cuz sometimes I just turn on my computer, quickly start a game and after a few secs it hard-crash and trip my PSU breaker)


Amd Phenom x4 2.5
Gygabyte AM2+ MA785GM-US2H

My friend fixed your problem with Fix 3 : Cleaning the Registry.

He used a registry clean software to delete that:

hkey local machine > system >
controlset002 > enum > root > *LEGACY AMDKMDAG*
controlset003 > enum > root > *LEGACY AMDKMDAG*
controlset004 > enum > root > *LEGACY AMDKMDAG*

There were 3 keys to AMDKMDAG!

He got used two registry clean software but these keys were not deleted.

He found a good registry clean software and deleted the keys and your problem with bluescreen-atikmdag, red square dot and vertical white lines is over!

If you use a registry clean software to do always a backup of all registry!

I hope that it help someone to solve the problem with atikmdag crash :)

I would constantly get full-stop crashes, sometimes I would get lucky with a kick to desktop saying my driver had an error and was restarted.

However just recently I have found much success with ATI Overdrive and under clocking my board.

I lowered my clock speed down a tad and manually set my fan to 70% - I will keep lowering it until I find my minimum but even at 70% it's not loud at all.

Cliff Notes:

Under clock your card and increase your fan speed.

Fix 4 - Stage 2 (Clock Speed) Worked for me.

I just had to set the minimum clock speed lower, and it has been working fine since.

CPU usage is at 0-1% idle, against 3-10% idle.

Thanks a lot for this

Thanks for this page. Sharing my information for the interested ones.

System specs:
Vista 64bit
C2D e8400@3600MHz
4870 512MB

I have had these issues only with some of the games - those games that have been bit more GPU-heavy like Crysis 2, Witcher 2, etc. I have never had problems with bit lighter games like WoW, DoW, Crysis1.

I did earlier done some GPU temp measurements and at that time they did not seem to have any affect on this issue. The GPU was running ~same temperatures with WoW and Crysis2, only the latter crashed within several tens of seconds whereas WoW never crashed.

I did do all these steps:
- cleaned registry
- removed that mentioned windows patch
- lowered default GPU clock from 800 --> 775MHz

Now, I can run Crysis2/Witcher2 with absolutely no issues, increasing graphic settings only slows the frame speed but does not crash the driver. Increasing GPU back to default values comes with all the issues.

So I vote for lowering the GPU core speed. Seems like these graphic card cores start to "wear out"...

Admin:  Thanks for the info!

I have just fixed this issue. I am using GTX 570 and running on Win7.

Solution: Swapped my graphics card into another PCI-E slot. Yes thats it!

Due to the big and hvy card, it may have worn off the slot so i swapped into a new one and it is solved.

Because my HP PC was running slow after 4 years,I decided to increase the Ram from 1 to 3GB. Then when running Rosetta Stone programes it started to go blank and I got the sign with atikmdag not working.

So after reading comments on this page I did the following and the problem seems to have gone away. I did it in this order.

1) uninstalled KB952287, rebooted
2) changed to Windows classic view rebooted
3) turned off user control rebooted and the problem has gone.

The program works as it did before. I don't think you need User control when you are the sole user. I hope this works for others who have the problem.

Many thanks for all the tips.

I believe it is caused by the TDR delay (win 7 and vista), I found something about it on the microsoft website and after playing around found this works 95% of the time. It does still crash, but probably about once every few weeks instead of every 5 mins.

Win 7 users -- Start -> Run (if not there ctrl, alt, del -> taskmanager ->file -> run)

Type regedit press enter, then yes on the user account control pop up.

Using the left hand pane navigate to HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control GraphicsDrivers. The right side of the window should have two keys, default and something about a kernal.

Right click an empty space below these two files. Select New -> DWORD (32-bit) Value, Rename it TdrDelay (case sensitive), next right click it and select modify. Change the default value to 7 and click OK. Exit the regeditor and reboot.

-- Note, YOU MUST CHANGE THE DEFAULT VALUE; if you leave it at 0 it will constantly reset the graphics driver. Choose between 3-9. There is an option to change the data between hexadecimal and decimal. I dont know the difference. Mine is on hex and it works, so does the 2 or 3 other computer i done this on.

IF IT WORKS FOR YOU DO AS I HAVE DONE AND SPREAD THE WORD! The hard part is done just copy and paste.



Admin:  Awesome!

Hello, found this workaround over another site (not allowed to post it)
Here is the workaround:

Open CCC and switch to ATI Overdrive
Unlock and enable Overdrive
Go to Options/ Profiles/ Profile Manager and create a new profile called, let's say, STABLE.

Save the new profile. But DO NOT ACTIVATE the profile.

Now go to C:Users {YourUserName} AppDataLocal ATIACE Profiles folder ( I assume C: is your system drive )

Note: You should have " show hidden files " turned on to see the folder.
Open the .xml file named STABLE with notepad.

Change the values of the idle Core clock and Memory clock speeds below

Feature name= "CoreClockTarget_0"
Property name= "Want_0" value="40000" note: previous value should be "15700"

Feature name="MemoryClockTarget_0"
Property name= "Want_0" value="90000" note: previous value should be "30000"

Save the file and close it.

Go back to CCC and activate the profile. This will make the card idle at 400 MHz core clock and 900 MHz memory clock.

It seems the problem is not overheating, but idling the GPU in very low voltages, causing it to become unstable.

Notice, that this workaround may increase you GPU temperature by 4%

Admin:  Many thanks for this solution!

I've had this problem for the last year too, same old Driver message....

My graphics are onboard (Nvidia on an Asrock K10N78 FULLHD-HSLI Socket AM2+ Revision 3.0)

The problems don't seem specific to any action, it will even do it whilst the PC is idle. But push Online HD video through it, use the zoom slide bar on Windows Photo Viewer, or Boot Up Adobe Photoshop and it will definitely give that error message.

In addition to the Driver message; sometimes it will just bluescreen me without any error message beforehand, then reboot. Worse still, the PC will sometimes bluescreen me, restart then do it again and again, to the point the PC won't boot at all.

However i have noticed that when it goes into this loop of bluescreens, restarts, bluescreens, if i turn the PC off for 20mins the PC starts fine and runs well for maybe another hour.

Perhaps this is not one select problem. I think at least one of my problems is overheating. I haven't yet tried re-doing the paste on the CPU and GPU yet, or turning Aero off, but will soon....

Admin:  Very interesting. Could you remove the side cover of your PC to help keep it cool? Then if the error stops you could definitely link it to overheating.

I have this problem with atikmdag.sys for more than 18 month after upgrading Vista to Win7.

My PC is running 24h a day and my finding is: After a MS patch day the problem is gone - until next reboot, power outage or software installation with computer restart.

This effect is repeatable. So I try to avoid installing new software shortly after a patch day.

How do I un-install the KB952287 file that is disturbing

Wayne   Vancouver, BC 

Sunday, March 27th, 2011

Some users have solved the problem by actually uninstalling a windows hot fix, the "KB952287" patch. (Vista Users)

This worked for me on my HP Tablet. I also disconnected the battery for half an hour and the problem seems to have gone away.

I also used to use a secondary monitor and have not reconnected it yet. We shall see what happens when I do.

This blue screen error is due to hardware overheatting. The solution, open up your pc or laptop and clean up the heatsink by removing it from the cpu.

At the time of installation, clean up the old heat transfer compound and apply new one. I recomment a non-silicone base compound.

I came upon this solution after extensive research, trial and error.

Also, remember to apply new heat transfer compound to all the components touching the heat sink.

I have suffered this "display driver atikmdag stopped responding" problem everytime I have tried to run Adobe Premiere Elements for video editing under Vista. Result - I gave up with the software (expensive!).

Suffered the same problem for the first time viewing a YouTube video today so looked again for a solution.

Found this page... All I have done is select the "Windows Classic" theme (see FIX 5 above) and the problem seems to have disappeared.

Many thanks to those supporting this page - such a simple fix.

Everytime I choose aero again the atikmdag or R200 driver stop working and restarts.

With eg vista basic instead nothing happens and problem solved.

Have win7ultimate, nVidia 9200M GS

Things that did not work for me:

- underclocking, mild overclocking
- old / new drivers
- turning off aero
- downgrading system color settings to 16bit
- using only laptop monitor, no external
- one memory module (2GB instead of 4GB)
- disabling sound driver
- uninstalling d-tools
- power setting on performance
- dusting the inside

I still need to try w7 without any patches but do not have time for that.

I used Riva Tuner and set the overclock on the max official values with 400 MHz on memory clock - Freeze kept happening.

Then I set the memory clock to 420 MHz and the number of freezez decreased (playing DA: Origins)! I could finally play without interruption.

Freezes still happened, but rarely and usually when the game was not intense, mainly when I was reading in the journal, thus it was not disturbing.

I was suffering from atikmdag error for almost a year, only to find the solution yesterday, after some intense reading on some other forums.

For ati users, all you need to do is uninstall the rest of the ati software except for the driver only.

Just go to control panel>manage software>choose customize uninstallation of ati apps> uncheck all other ati apps except for the driver. And thats it, problem solved for me.

I learned that atikmdag error because of the ati catalyst control features that is executed from startup.

I had this problem for 4 months. My system is a Toshiba A350-22Z. It has cool specs.

I encountered this problem when I enabled the Intel Dynamic Acceleration option in my BIOS. Then I started having video crashes.

I thought it was the OS. It was originally installed with Vista OEM. So I changed the OS to Windows 7 but still have the same experience. Now, as I was browsing this article, I remembered turning that "dynamic acceleration".

So, it must be the "overclocking" that is causing this trouble. I disabled it and it came back to normal. but i will observe this in the coming days. hope you find some ideas.

I have another information for you (unfortunately no fix).

I´m using dual boot MacOSX 10.6.4 and Windows 7 64bit.
MacOSX use some "special" drivers for 5xxx cards. everything worked fine.

Then after watching a youtube video (in MacOSX) it froze. I had to reset the PC.
After resetting OSX isn´t booting anymore (only in safe mode).

Windows isn´t booting also. It hangs up before login screen with the atimkpag.sys BSOD.

So Windows and MacOSX hang up just before login screen.

So for me it looks like:

1. hardware failure (but why is it working then in safemode with full resolution)

2. some sort of graphics RAM failure.
Maybe it could help to some sort of reset the graphics card.

Do you know if something like this is possible?

Thanks in advance!

The following issue is a software issue caused by an incompatibility between the acceleration of the 2d Windows Desktop and Certain acceleration products from ATI/Nvidia.

XP Users fix: Right click desktop -> Properties -> Settings Tab -> Advanced -> Troubleshooting -> Set the hardware acceleration to "None" -> Apply -> Restart Computer.

Vista/w7 users: Right click desktop -> Personalise -> Display settings -> Advanced Settings -> Troubleshooting -> Set the hardware acceleration slider to the lowest -> Apply -> Restart.

XP users are recommended to load their OS into "VGA mode" using the f8 boot selection system that is activated by pressing f8 before windows starts loading.

I ended up installing Windows XP and i have never had the problem again

I have been having this issue and tried this: Went to Control Panels/Power Setting...then changed to High Performance instead of Balanced. So far so good.
