I recently purchased an EVGA GTX560ti Superclocked edition to replace my old GTX260. For a couple of weeks I had no problems at all, but then overnight (after a driver update to 296.10) my computer blue screened. Over the next 24 hours my computer blue screened twice more, so I rolled bak the drivers to the previous version (295.73) which has solved the problem. However, now I'm getting computational errors on ALL CUDA projects. CPU run projects are fine, but GPUGRID, EINSTEIN, SETI..etc all cause a "acemd.win.2352 has stopped working".
Any people out there have the same issue, and do you know if there are any other previous 5xx drivers that work properly for CUDA apps?

Thanks

The newest BETA version should have solved several issues.

If you have Windows -> http://www.nvidia.co.uk/object/win7-winvista-64bit-301.24-beta-driver-uk.html

Many thanks. It's been running for a few hours now without issue, fingers crossed, thanks again.

The problem is that 295.xx and 296.xx drivers sleeps the CUDA engine as well when the monitor go to sleep.

Either install the beta version of the graphic drivers (like you did), or disable sleep timer for the monitor (like I did).
