Thank you Ageless. Indeed that was the issue. I could have sworn that in my previous built I was running BOINC as a service and GPU computing was working but obviously I am wrong... :(

In either case, that was the issue and now my GPU is happily computing...

Cheers!

After reformatting PC with Windows 10 Pro 64bit, Boinc can no longer see the GPU.

System Information:
Windows 10 Pro 64bit
Boinc 7.6.33 x64
NVIDIA GeForce GTX 760
NVIDIA drivers 378.49 01/24/2017 (latest) installed through GeForce Experience

With previous installation (Windows 8.1 Pro 64bit) and GeForce Experience, latest NVIDIA drivers etc everything was working fine.

Typical startup log:
23-Jan-17 1:42:19 PM | | Starting BOINC client version 7.6.33 for windows_x86_64
23-Jan-17 1:42:19 PM | | log flags: file_xfer, sched_ops, task, coproc_debug
23-Jan-17 1:42:19 PM | | Libraries: libcurl/7.47.1 OpenSSL/1.0.2g zlib/1.2.8
23-Jan-17 1:42:19 PM | | Running as a daemon (GPU computing disabled)
23-Jan-17 1:42:19 PM | | Data directory: D:\BOINC
23-Jan-17 1:42:19 PM | | Running under account boinc_master
23-Jan-17 1:42:19 PM | | No usable GPUs found

Nothing that I have found on the message board seem to help me. Can you please help?
