One of a new problem that you will experience in Windows Vista and Windows 7 but not on Windows XP is the screen going black for a few seconds and then comes back on with a popup notification telling you “Display driver stopped responding and has recovered. Display driver nvlddmkm stopped responding and has successfully recovered.” From the message it does seemed like the driver has crashed and most of the time neither upgrading nor downgrading the driver will fix the problem. If you search for this error in Google, you will probably end up with hundreds of threads to read and with some really ridiculous suggestions such as reformatting your computer, sending back the graphics card to manufacturer, etc.

The good news is you don’t have to go through that because SilentBob420BMFJ has already went through all the hard work which he finally found a workaround that fixes the problem and shared it in NVIDIA forums. Thanks to FunkY for finding that as well and posting it in our forums to help BigGuy.
The simple trick is to set a fixed graphics card for PhysX processor instead of letting it auto select which may end up selecting your CPU and causing the crash. Go to Control Panel > NVIDIA Control Panel > Expand 3D Settings > Set PhysX configuration. At the select a PhysX processor, by default the “Auto-Selected (recommended)” setting is selected. Click on the drop down menu, select your graphic card and click the Apply button to confirm the changes.

This simple solution should be your first attempt to fix the problem before reinstalling drivers, replacing nvlddmkm.sys driver file, fixing registry, uninstalling windows patches and etc.

i have a power solution. url here : somemorebytes.com/wp/index.php/software/nvpmmanager/
I used to have this problem on a WIN7 pro / Lenovo 3000N100 laptop when i browsed the internet with Chrome.
The solution i found that stopped this error (almost completely) was to disable Transparency under Personalization > Windows Color and Appearance.
Hope this work for you too.
I changed the setting, chosen my card GTX 560 as the choice. However several hours later I still get Nvidia Display Stopped Responding issue while browsing online.
Funny thing that is you show the settings under windows XP :D
My ndvidia control panel don’t have “Set the physics configuration”, now what should i do?
Raymond!

This NVIDIA snafu where my monitor crashes on and off has been a real THORN in my side for about a year now when I first purchased my ASUS computer. I tried looking at all the forums looking for a solution that would stop the display from literally Blacking OUT!
(I do not blame ASUS for the apparent faulty display as I do LOVE my all solid-state laptop – - and I recommend said brand rather highly!)
I just followed the above instructions this evening and am waiting to see if it will soon be smooth sailing henceforth with the result being that my monitor no longer crashes.
. . . In the meantime, A BIG THANK YOU to You and Your Forum buddies for giving us a True Simple Workaround to this Mess! I am very Disheartened that the folks at NVIDIA could not or would not provide the solution!!!
(I am more than certain that many others have complained to NVIDIA about this crashing issue)
Again, Thank You SO VERY MUCH.

Only GeForce Series 8 and above have PhysX settings (from nVidia Control Panel Help menu). My GeForce 7600 GS doesn’t have have Set PhysX configuration in the 3D Settings.
My display goes black for 2 seconds then comes back (without any error messages) on my HP P6520y about a dozen times a day. So far cannot fix it.
Originally I had ATI Radeon HD 4200 integrated graphics that had the isssue. So installed the GeForce 7600 GS card, but this has the same issue.
Two cards from two different manufacturers, yet I get the same problem.
Any ideas on how to fix this? I have tried for months.
It’s because your motherboard support hybrid crossfire, you should have gone with ati 4000 series graphics card for best performance.
Thanks avi singh. Sat Siri Akal. Originally I used the onboard ATI Radeon HD 4200, but this had the issue, that is why I tried an nVidia card which also had the issue. Since both these cards have the issue, that means the issue is either caused by the motherboard or Windows 7. But how do I fix it? That is what I have not been able to figure out. Another factor might be the Belkin OmniView Pro 8-port KVM I am using. Perhaps there is an incompatibility. I have another PC of this same model HP that is not on a KVM and it does not have the issue. I have yet to try this PC without the KVM to see if the issue goes away. But that wouldn’t help much anyway because I do need to use this KVM.
I don’t have Set PhysX configuration in the 3D Settings
I only have Adjust image settings and Manage 3d settings
just you get the driver update from nivida website . when you get that you will automatically get installed PhysX configuration
I love my iMac
loool
