nvlddmkm stopped responding

When I play a game. It is annoying me.

Anyway to fix it?

I get this as well. It seems to be endemic to nvidia and vista.

I found some old posts on the nVidia boards complaining about this - At least according to those, the issue was solved by the later drivers - 169.xx Partially or not, I don't know...

So try updating your drivers.

Scotteq,

Thanks for the advice. I've been running the 169.25WHQL drivers since they were released. My main games are Company of Heroes (and the expansion, Opposing Fronts), World in Conflict, and Crysis.

The nvlddmkm issue has raised it's ugly head intermittently since I began using this machine with Vista x64. (Note that Vista Ultimate x64 is the ONLY OS ever on this machine, so I cannot isolate the issue away from the OS. It is a variable that I have not changed, nor am I willing to swap operating systems for the sake of troubleshooting.)

The nvlddmkm problem goes away for a period of weeks, then reappears. Once it comes back, it continually comes back, even if not playing a game. In fact, I believe it will occur with no extra process going on. (By that, I mean that _I_ am not clicking, pressing, or entering anything. I defy ANYONE to accurately assess what Vista is doing with or to their system at any given moment.)

I hard reboot pushes the nvlddmkm problem away. For awhile.

The prevalence of this issue is distressing. The main thoughts seem to be hardware incompatibilities, driver issues with nvidia, Vista problems. So, other than what's in box, what's operating the box, and items used by the box, there doesn't seem to be anything else to cover!!

Cooling, voltage, etc., doesn't seem to be at fault.

Thanks anyway.

This has been driving me nuts too. I have tried running Company of Heroes and the expansion pack on various levels of detail on DX10 and all settings have caused the error message to appear and the game to finish. Once I revert the settings to DX9 on maximum settings its fine for hours on end. I have heard its the Nvidia drivers at fault. I have tried the latest drivers and the latest beta drivers as well to no avail. Guess we are in the hands of Nvidia to sort it out with the next release of drivers.....

Hi Guys,

try removing the Nvidia network access manager (firewall interface)

LOOK HERE:

Have you guys that are experiencing this got this hotfix:

An update is available that improves the compatibility and reliability of Windows Vista

Seems it solved a lot of peoples problems with this error.

Let me know if it has fixed it for you or not.

I dont think that this is available via Update, but I believe will be part of SP1 when it is released to the general public.

coolchris,

Thank you. That hotfix is one that I've tried before, but I cannot load. I try to, but get a message, the gist of which is that it is not needed, or doesn't apply to my machine. Something like that. Regardless, it's not a UAC or corrupted download issue. It's an OS level refusal to run it, I assume due to valid reasons.

That is one of a series of three. The only one which did take was kb940105.

I hope it helps someone.

Thanks.

Yer, if it comes up saying that its not needed, it means thats its already installed. Hmm, head scrathin stuff. Have you tried to uninstall the driver completely..by that I mean uninstall it, then run a driver cleaning app like this one below to get rid of all the dross:

Guru3D - Driver Sweeper (Setup) download from Guru3D.com

See, when you install new drivers over the last one without cleaning out the previous ones can cause conflicts.
Have a go and let me know.,,

Coolchris,

LOL! Yeah, I've done that. You're giving excellent advice, and I do appreciate it!

I thought I'd licked the nvlddmkm problem several weeks ago because it hadn't occurred during that time span.

I have a mild overclock on my q6600 (from 2.4 stock to 3.2), but a LOT of cooling. I also have 4x2gb ram. I've ensured my Vram is at the rated voltage, and to help my Abit Ip-35 pro I've upped the MCH volts to 1.33. (And the nvlddmkm issue had popped up BEFORE I overclocked the processor and adjusted RAM voltage.)

I am a bit puzzled. I can run Crysis in DX10 with all settings on max using 1920x1200 resolution. .(8800GTX at stock with extra cooling/heatpipes.)

Right now I have a sense that this is related to Company of Heroes. I am going to see how long I can run without nvlddmkm cropping up. If it runs well for several more days, I will start CoH and see if I then get instabilities.

I mention all this to show that the machine has plenty of horsepower and cooling. (Some folks believe the nvlddmkm is an issue related to overheating.) If Crysis doesn't overstress it, I don't know what will.

If CoH causes problems that could be a software fix isolated either to the game or the nvidia drivers being used by the game.

Keep the suggestions coming.

Thanks,
Ken
