Ive just updated my boinc version to 6.12.26.
Upon completion of the update I restarted my computer and now boinc does not find my GPU:

Until now BOINC has always found my GPU, Any ideas? Im going to try a rollback in the meantime

The GPU is a Radeon HD 5650

That's your problem!

Uninstall BOINC and reinstall with the "Protected Application Execution" box unchecked (advanced mode?).

Thanks! :) That fixed it, however I am somewhat confused. I have that same setting selected on my desktop and its graphics card is found just fine :/

You can run in 'protected application execution' mode in Windows XP, but not in Vista or Windows 7.
