Need A Little Help Here!

I have a had a problem with my high end Nvida cards for the past 2 years and you guys are the best techs I know, so I need your help. First off, don't start with an Nvidia an ATI war because the research that I did proved that BOTH companies have this issue. Ok, when I first buy the card, everything works great for about a year or so then I start to have the issue. I currently have an Nvidia 480 GTX card and recently have had the reoccurring problem where I crash back into the desktop while playing a game. When I check my taskbar after the crash back into Windows, it tells me that NVLDDMKM.SYS has stopped responding or has crashed and could not recover. Did any of you guys ever have this problem? Apparently this problem is rampant and if you Google it, you'll see that hundreds if not thousands pf people have had this same issue and it has been an on going problem for many years. Now, this is what I do know about the issue. While it has been suspected as a voltage problem with either the Ram or the PSU, this is not the case. Apparently, this is a driver issue due to the fact that the newer drivers marked NVLDDMKM.SYS in the system 32 folder can't seem to play nice with the older ones (even though they are rewritten) and causes this error. One fix was to change the name of the file from NVLDDMKM.SYS to NVLDDMKM.OLD. While at times this has worked, it's either a hit or miss and when I purchase a new card and the problem starts, it's a coin toss whether it will work or not. I also do not know why at times when I have purchased a new card the problem does not happen for about a year or so (this might also have something to do with the integrity of the card itself after said time of being used). So basically I just wanted to see if any of you guys have experienced the same issue and whether you have found a fix or not. As I said above, you guys are the best techs that I know (next to myself ;-) ) and I wanted to run this by you guys and get your thoughts on this problem. Thanks for the assistance.

Download the new beta drivers that reid had posted earlier in his post here.
then follow the guide on the nvidia forums to do a fresh uninstall of the old drivers and your current ones here.

You also always want to make sure you clean off the heatsink/fan combo on your video card, as well as your case, just turn off your rig, pull out the card, be careful when holding it and use some canned air on it to the best that you can. (this will help with heating issues). if you're having a voltage issue, download a tool to monitor your temperatures on your cards so you can see how high you're getting during gameplay and when you're idling.

I have the same issue with my ATI, but mine is due to overclocking the card for 4 years and it now can't handle much of the newer games because of how much usage it needs (this is why i call CoD series garbage, because it can't kill my already dead card).

If this still doesn't work you can always attempt to do a fresh windows install after backing up what you deem necessary and see if it was a conflicting issue with other drivers or the windows kernel got fubar'd at some point.

Are you over clocking anything? I mean due to the duration that the error dont start for almost a year, I would say it could be a Overclocking / Heat issue. Before you go drastic try default everything and add as you go.

I am overclocking but very little. My chip can be OC'd to over 4 gig with no issues and I am barely even pushing it past it's min. setting. I have a QX9650 that is meant to be overclocked but as I stated, I really am not even pushing it even close to what most people do. It's possible it is a heat issue due to the fact that it happens like you said, after long use of the card, but this really does seem to be a driver issue. Thanks for your input though Russ, much appreciated :thumb: .

Also make sure you voltages are set correctly overclocked or not. Incorrect memory voltages gave Carver video card issues forever until he figured it out!

One thing that I did seem to find just the other day that really did help was a forum link that suggested that UAC (user access control, not anti cheat) be turned off.

Yeah, I should have realized that. UAC with Vista is horrible. Thanks again though Chris and Russ for your assistance.
