Opengl Lost connection with display Error 7

[Rose Munson]

I keep getting this error but it is not consistent just randomly.

 

I have a nvidia gtx 660  with windows 7.  Never had problems until recently any suggestions please.

Maybe in this Q&A?

My first thought is your video driver might be recently updated, maybe you should roll back a version.

[Rose Munson]

Well I had not updated for sometime I was on 310 and then 314 i did not have problems with those. I updated to 331.82 had problems with that one andthen 332.81 and got problems with this one.

[Kwakkelde Kwak]

I have to say NVidia doesn't make it very easy to find, but you can download the 314.22 driver from their site. If it doesn't fix your problem, you can always update to the most recent version.

btw, I can't find a 332.81 driver anywhere. My driver is 332.21, I think that's the latest one.

[Rose Munson]

Istill have the314 file on my desktop.

 

I may then do a clean install and go back t0 314.

 

I don't understand why I am getting the this error and then thedisplay is recovered albeit SL was shut down.

 

Is there something wrong with the opengl in second life?

[Kwakkelde Kwak]

I really can't say if there's something wrong with openGL in SL.

All I can say is I never had any issues since july 2012, running a slightly faster, but similair GTX670, always with the latest drivers.

So I'd say it has to be a combination of factors.

 

btw, how did you update your video drivers? It's best to remove the old one completely, restart windows, then install the new one. Or was that what you meant by a clean install?

[Rose Munson]

No I used the clean install option on the Nvidia installation.

 

Should I try that option uninstalling the driver first now?

Actually what exactly do you remove first, all drivers or just the display driver?

[Kwakkelde Kwak]

Just the display driver should be enough.

Out of curiosity I went on Nvidia support forums to see if any other information about this bug. I did see this

**************************************************************

Might be related to a recent opengl bug reported.

Memory Leak in DX_Interrop extension.

It will be fixed in the next driver.

Also they said the bug surfaced in the 314 driver
