GPU Cannot Find Enough Resources

[ktchify]

My GPU suddenly stopped working and I don't know how to fix it
"This device cannot find enough free resources that it can use. (Code 12)

If you want to use this device, you will need to disable one of the other devices on this system."
Here is a screenshot of it: http://imgur.com/BqK6USi
