Hi

Recently I updated BOINC and my Nvidia drivers, after this update I can't run any GPU tasks. It runs to about 10 to 17 % and then stops and I have this message:
2017-02-11 16:45:28 | SETI@home | task postponed 180.000000 sec: Cuda initialisation failure, temporary exit

I reinstalled BOINC, installed the older version, reinstalled Nvidia drivers. Nothing worked

I have a GTX 980ti with the newest 378.49 drivers.

Anyone can help?

CUDA is a part of your GPU, and is activated by the drivers. It being seen as missing or unable to initialize is a problem with the drivers. Reinstalling BOINC won't help in this as BOINC itself doesn't use your GPU, nor does it add any functions to your GPU.
Reinstalling drivers is the only thing you can do, and if newer drivers don't fix the problem or even cause the problem, then you'll have to try to install older drivers. Also install drivers from the GPU manufacturer, Nvidia in this case. Do not let Windows install them.
Try to install the drivers with a clean install. This is an option in the driver installer, so do a custom installation and read all the screens.

clean install didn't help, but installing older drivers solved the problem, thanks

To add a bit more detail, it has a problem on machine with a pair of 980ti 's and setiathome v8 8.0 (cuda 42). Other machine with a pair of 770's runs setiathome v8 8.0 (cuda 32) fine. So its specific to cuda 42 on the 980ti and the new driver..

NVidia has produced a hotfix driver that appears to fix the problem on 980Ti and other high end nvidia cards.
Details here:

I've installed it, and many CUDA based seti@home work is underway again without postponement or other errors.
Will let you know if I run into other issues.
Cheers!
