Well ,I have a solution for you and may be much helpful for you. You have to issue some commands but before that just put your driver in "Maximum Performance" mode but (hopefully) will stop the blinking.
Then issue the following command with proper option and specifications :
The code suggested above will create the file located /etc/modprobe.d/otions.conf with some bonded commands which triggers "Maximum Performance" mode.
echo 'options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222" ' | sudo tee /etc/modprobe.d/otions.conf
