I want to share a little about what I’ve learn from this driver error. The main culprit for me was the Fusion HDTV 5 TV tuner which had a “Power Up” cable that I plugged onto 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. Compare this with what others are experiencing, 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. It’s a generic error message that applies to most display problems. It’s basically saying “Something caused your video card to crash…” whether it’s ram issues, overheating issues, or simply a bad video card… So 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.
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. I’ll keep you posted.
