If that didn't help you and you keep having issues, increase "bfactor" to 8, "bsleep" can be increased to help as well.
Also, you need to adjust the "threads" and "blocks" to get optimum performance from your card. (Adjust, settings, save, run miner and check hashrate after a minute, then shut it down and adjust again, etc.)
You can also right click on the Start button and open a command prompt (shell?), cd <path to your mining software>, then xmr-stak --help. This will give you all the commands you can use to start xmr-stak in a .bat file.
