I have just seen an error message I am not familiar with on CUDA50 tasks. "Postponed: Cuda initialisation failure, temporary exit".
Running windows 10 with latest Nvidia drivers.

Any suggestions please ?

Something may have gone wrong with the driver or the GPU. A reboot may help.

It would appear that windows 10 update has attempted to force install a set of Nvidia Drivers (even though they are older) on my system in the back ground, but they have stuck and will not complete the install. Everytime I reboot Windows update tries again. I might have to go back to yesterdays backup.........

Some things can corrupt the hidden ./ComputeCache directory and all the gpu tasks will quickly error out. This can happen with either the CUDA or OpenCL drivers. I trashed about 50 OpenCL gpu tasks recently and a deletion of the driver ./ComputeCache directory files and restart of BOINC cleared things up. The tasks errored on the "too many exits" error.

The directory is in different places for Windows and Linux. Use your File Manager to search for the location.

Reinstall the right driver (clean new DL from NVidia site only) and not forget to choose the clean instalation. That is the only way you could be safe all is in it's right places and nothing is corrupted.

And remember: Never allow M$ update your video driver.

You really should turn off Window 10 automatic updating of manufacturer drivers. You do this through the System Properties application and the Hardware tab.

Select the Device Installation Settings property and set it to No for the "Do you want to automatically download manufacturers' apps and custom icons available for your devices?

You won't ever have Microsoft download their own versions of the graphics drivers again. Just get any new graphics drivers directly from the manufacturer download sites.

Keith, this is good advice that I will be following as my system got completely hosed. The windows update database got corrupted and was logging all updates as being installed on the date 01/01/11, one update had been installed 19 times. I ran the troubleshooter which said it could not fix the issue, then SFC and DISM commands - but they found nothing wrong. I tried renaming the database file so that windows would create a new file - still no good. So in the end I swallowed the bitter pill and went with the clean install route.
