More information about nvlddmkm stopped responding and has recovered error.

A little information about this error. The main culprit for me was the Fusion HDTV 5 TV tuner which had a “Power Up” cable that I plugged into the motherboard. After installing that TV tuner, I’ve started receiving errors while watching movies, but never during games. Once I pulled the “Power Up” cable out, everything was back to normal. Most people get the error while playing WoW (World of Warcraft) or other heavy graphical games. It’s obviously something different that’s causing the problem. My point I’m trying to make is that the nvlddmkm error isn’t a specific error or unique error. Instead it is a generic error message that applies to most display problems. It’s basically saying that something caused your video card to crash… whether it’s ram issues, overheating issues, or simply a bad video card…There isn’t a single permanent fix, just many fixes for many different causes. Also, it isn’t just a nVidia problem, ATI receives the same error in the form “atikmdag stopped responding and has recovered.” Some people have reported that switching over to ATI seemed to have worked for them. From what I’ve seen, it doesn’t matter if you have ATI or nVidia. It worked for them mainly because they had a bad video card and got a new one. Suggestion: get your video card RMA'ed
Also, you might be asking: When I install XP, everything is fine, but in Vista, I get this error. This is a sign that the problem most likely doesn’t lie in the hardware, but the software. Your first step is to increase the timeout in the registry for the error and then disable nVidia’s PowerMizer setting in control panel (read my solutions below for more information).
Hopefully that explains a lot.

Method 12: Disable Dreamscene

I’ve thought I posted this already, but I haven’t. Anyways people have reported that disabling Dreamscene (playing video in the background) will fix the problem. Disabling Dreamscene: Go to appearance and personalization in Control Panel, select Personalization select Desktop Background, select any thing other than Windows Dreamscene Content. Select a background and click Ok.

Method 11: Disabling Powermizer

Thanks to skym0903 for this tip. Disabling nVidia’s Powermizer feature may help move this error. He says that whenever he gets this error, he notices that the core clock changes. The reason for this is that the Powermizer feature down clocks your video card to save energy. Perhaps changing clocks in the middle of the game might be causing the nvlddmkm error so disabling the Powermizer feature will remove the problem. To turn this off in Windows Vista follow this link.

Method 10: Remove unnecessary power from motherboard.

In my previous solution (method 9) I’ve suggested to remove PCI cards (mainly TV Tuner cards). The problm was not the pci card itself but the external power it needed. There was a connector that I plugged in from my PCI card to the motherboard. When I removed the PCI cards, the power connector was removed. Now I’ve re-added the TV tuner cards without plugging the external power and everything is fine. Check your power plugs and remove any unwanted power!

Method 9: Remove PCI cards

I’ve been trying things with my computer since this error won’t go away. I have a FusionHDTV 5 PCI HDTV tuner and a Pinnacle PCI HDTV tuner. I’ve removed both and the error has stopped so far. So try removing all of your PCI cards and see if the error stops. Then add the PCI cards one by one back. If the error comes back, then you’ll know which PCI card is bad. For me, the FusionHDTV 5 was the bad card.
