Windows 7: Display driver nvlddmkm stopped responding.

Formatted my computer today and installed the latest drivers.

Now I get the error below at random times, screen goes black, then comes back on.
"Display driver nvlddmkm stopped responding and has successfully recovered."



This didn't happen before I formatted.

Any ideas?
As this is a completely fresh install I'm not sure what could cause it.

sometimes you just get a bad driver installation.
As a first quick step you can try just running the driver installer for your graphics again, you can track it down here. Drivers - GeForce
If a reinstall over what you already have doesn't clear it up you'll need to go the long way....

Do download a fresh copy of the driver even if you have one already.
after removing the nvidia display driver normally in program and features, follow up with this program.
Phyxion.net - Driver Sweeper
in Safe Mode (you want it to pull the nvidia display drivers only. it will give multiple options.

After doing that reboot normally and then reinstall the driver. You also have mixed cards I noticed so you may want to make sure physx isn't screwing up somhow.

I thought this might cause problems, the 210s only use is for a 3rd monitor via HDMI (which is my TV), currently nothing is plugged into it. Probably shouldve taken it out before I reinstalled windows -.-
How would I check if its causing the physx to screw up?

I'll try do a clean install of the drivers in the mean time. Thanks for the reply.

Sigh >.<

Nope, still happening.
Is there a mirror for driver sweeper, It's downloading at 2.0kB/s from that link.

How would I downgrade to a previous version?
I never had this problem with my old drivers.

To be honest I would remove the second card if it is not in use. Heat, power consumption... lots of reasons even outside possible conflicts it could cause.

Well, I had that second card in for around 5 months without issue. I still use it when watching streams / movies etc.

If I still have a problem after using the driver sweeper, what else can I try?

If your sure you have the right driver from NVidia you can do the custom install which uninstalls the old driver for you and then installs the new one. As said above it's best to have one card in when installing the drivers then after making sure it works reinstall the other card.

Are you getting any BSODs?

Also check Event Viewer for errors.

Not getting any BSODs.

For some reason the default DirectX was set to DX9, after switching to DX11 it hasn't crashed since.

Is it possible for older DX versions to cause this problem?

Where was you setting for DX9? DX9 is a subset of DX11, and I would have thought your only option was DX11. If you run "dxdiag", it should report your version of DX.
