On my previous computer with win 7 the manager detected my gpu and was running on it. My new PC does not detect the Nvidia GTX 850M and all the prohjects are running on CPU. How can i fix this?

a) you need drivers installed from the Nvidia website to get the GPU detected correctly, Windows installed drivers lack components required. http://www.nvidia.com/Download/index.aspx?lang=en-us
b) make sure you didn't install BOINC as a service, as then GPU detection is disabled due to the drivers being in another plane than the user's account is. That is a Windows security measure, it's not something BOINC can fix or work around on. You can recognize if you installed as a service when one of the first lines of the Event Log (SHIFT+CTRL+E) shows "running as a daemon".

To fix that, uninstall BOINC, reinstall it and in the third screen of the installer click "Advanced", then uncheck "Install as a service" (read the blurb) and continue installation.
c) make sure the project(s) you run have that computer set on a location in which the correct GPU is enabled.

Thanks, the service install was the problem.
