OK, so you have Intel Haswell i7-4790, which has an Intel integrated HD 4600 GPU, which is more powerful than the Nvidia GT 610 
I'm quite puzzled why on earth are you even using that Nvidia card at all? From all this that was written up until now, my recommendation would be:
1. either physically take out the Nvidia card from the Tower and use only integrated Intel card
2. or if you cannot take the Nvidia GPU out, switch back to proprietary Nvidia driver and via it, switch to the Intel integrated card, either via the Nvidia GUI or via command
3. now that we would have the Nvidia crap sorted out, we go back to the kernel stuff - if I were you, I would remove the 4.9.9 kernel (because it's not tested thoroughly and it can be quite unstable) and install the one from HWE, so 4.8, which is much more stable and thoroughly tested.
4. to set the threshold parameter properly you would first need to switch to root, so follow the commands:
That should do it. But before changing that parameter, try the first 3 steps, I'm quite positive that your troubles might be solved by that.
