**Original Title**nvlddmkm.sys causes BSOD
Hi,
I can't start Vista since a week or so. Just before the login screen should apear, it crashes into a BSOD, reporting that the problem is the nvlddmkm.sys driver.
I've been checking the Internet for days now (a lot of forums), and it seems to be a "common" problem, occuring with all kinds hardware and software configurations. I've tried just about everything to fix it, but nothing seems to work.
Is there a solution for this problem?

Hi Maarte61,
Sorry to your having so much trouble. Since your having the same issue even when the driver was rolled back, it leads me to believe even more so, that it could be card itself. You might try contacting the cards manufacturer. We could rule this out though, if you have another video card we can try. Do you have one you could test?
Thanks again,

Hi Maarte61,
Unfortunately, my guess would be the driver or the card itself. Since it worked fine for while, then just stopped. My best guess would be the card's the issue. Can you cancel the driver install when you get to normal mode? If so, I would try canceling it and downloading the new driver. Or if your in "Safe mode with networking" I'd go ahead and download them them and have them ready. So if you can cancel, you wouldn't have to go download them. Let us know and thanks again for posting.
Thanks,

Hi,
Thx again, Mark. I already tried all my restore point. Also did the driver roll-back. In fact, I always keep a copy of older drivers, in case the new one causes problems (and too lazy to delete them :-p). I have 6 previous versions of the nVidia drivers, and all of them fail. I also deinstalled a lot of programs already and disabled startup programs and services (using msconfig). It seems the BSOD only apears when I've enabled the nVidia display service/startup.
In the forums I read people even completely reinstalled Vista, and still had the problem...

Lot's of folks are running those nVidia drivers on Vista without that error. Those other users you have found having this trouble are probably all running some other device or driver causing a conflict. My approach would be to disable all unneeded devices temporarily in device manager, and restart. Then add back in one device and driver at a time till I spotted the conflicting device driver.

Hi,
I agree. Even more people run without any problems at all. Like I did, for more then a year. Then, it appeared, for no reason at all. idn't install any new programs or hardware for a substatial period of time. I was browsing the internet, and my PC crashed. No aparent reason at all. I was able to boot normaly for 1 or 2 days, but the crashes came mote freqent. And now unable to boot, only in safe mode.
However, an awefull lot of people DO have this problem. And an awefull lot of them can't fix it. Haven't been able to, for serveral weeks.
Disableling devices? Why? I bought a pc, switched it on and it worked. For more then a year. What devices should I disable?
I think nVidia and Microsoft should take their responsibility, get their acts together, join their efforts and release some kinda resolution asap. Male it top priority. Seeing how many ppl suffer this problem, seems to me it should be top priority.
