Windows 7 - Windows 7 RC + nvlddmkm.sys BSOD

I have had a similar problem with my 2 XFX 9800GTx+ in SLI and by themselves. Except it only happens under a heavy load in a game. Would this also be a tdrdelay problem?

It doesnt memory dump, but it causes constant hangs which only ctrlaltdelete fixes temporarily in game, then continues to do it over and over again until eventually i get the nvlddmkm problem.

Hi! ^_^

I've just upgraded my PC from Beta 7048 to build 7127 and get this problem too. Using nVIDIA drivers v185.85 give me that same error. Mainly when I play videos on Media Player Classic using EVR Custom Presenter, that uses graphics card for video processing, screen flashes for 1 or 2 secs. and then shows the BSOD with nvlddmkm.ddl.
Going to try that tweak that Jutajata shows to us and I'll come back to tell you what's up.

Looking forward to your results.

Sounds a lot like it nuluis it could very well be. We can only hope that nVidia works to fix these issues. We must remember that even in Vista upon its release these problems were all to common.

Well... after trying too much combinations I just gather the possibility to delay a little the video driver restart process before it shows the BSOD. I mean, I can't fix the error yet.
I want to get my games working again before one of my head's veins explode!

Ive noticed that a lot of people are getting problems with the 185 nvidia drivers and get this solved by downgrading to 181, try to disable the tdr using the command TdrLevel 0 in registry, im an old ati (1900Xt) user and this fixed the issue for me until good drivers are make.

Cheers

I had seen that fix using TdrLevel=0, but I didn't tryed with it because I tought that it would generate even worst results. But now, let's give it a try.

So did it work?
I'm getting the exact same error. And I'm only getting it when I'm using EVR custom present in MPC HC.

I'm forced to switch to Renderless WMR9 to stop my windowns from crashing. I really hope the next nvidia drivers fix this...

I am having the same issue installing windows 7 after splash screen BSOD. And now there is nothing I can do about it...You can't get any futher into the install because it never completes. No safe mode no nothing....this is so frustrating....Can Nvidia ever release good drivers...I mean what do they do there....I've been a gamer for 10 years now and I haven't seen them release flawless drivers for any platform....ever....


Sorry, just ranting, but I was enjoying my systems just fine until they released this crappy driver....Now I'm back to square one with none of my systems working correctly except my laptops.... Any fix would be greatly appreciated. I would love to try the registry fix but since I can't even get into windows, I am a sitting duck....

Hi again! I've good news minna! ^o^

I've reinstalled Windows 7 in an attempt to get MPC HC with EVR Custom Presenter working. This time I have installed build 7137 and get the same error, with & without the 185.85 nVIDIA drivers. But I've solved the problem easily. Seems to be something wrong with the H.264 decoder built in Windows 7 (try to play something in WMP12 and you'll get the same error).
So, to fix the problem, just go to Programs -> K-Lite Codec Pack -> Configuration -> ffdshow video decoder. Once there, in the left-side options click "Decoders" and change the "H.264/AVC" codec from "disabled" to "libavcodec". This will allow you to use the EVR Custom Presenter again without problems.

Hope it helps you all and leave comments to know if everything went well!

have u installed any driver after installing rc??
are u using build 7100??

if u are using 7100 run windows update. there u will find a hotfix that will probably solve ur issue.....

and due to some reason u cant do that then open the windows in safe mode then open run, type msconfig. now in msconfig open services and select "hide all microsoft service" then switch off all the services that are present....
and disable all startup programs....
ur windows should boot in normal mode...
