Just downloaded the latest version 7.0.64. I also have the latest Nvidia drivers 326.80 (beta). I could swear GPU crunching used to work on this card. This card is a CUDA card. Any ideas?

How did you install BOINC?
When as a service, BOINC won't be able to detect GPUs.

You can recognize if it's as a service when you check in the Event Log (CTRL+SHIFT+E) and see running as a daemon in the start up messages.
The only way to then get it to run normal is uninstall BOINC, install again from the installer, in the third screen click Advanced and uncheck the "Service Install" option, then continue installation.

Furthermore, the drivers that you have must come from Nvidia. Drivers installed by Windows lack the CUDA and OpenCL components.

Yup that was the problem. I installed as a service. Re-installed and cuda is working! Thank you!
