Nvidia's drivers and their control panel seem to have become really flaky. Try using nHancer to set up your profiles and run the card, it is far more stable and gives more options. The only things nHancer will not do is set your fan speed, check the GPU temperature and overclock the card. If you want to do those things you will have to install other programs or use RivaTuner instead of nHancer.
