There appears to be a number of problems here: The Intel 7700HQ is a Kaby Lake CPU. It seems that support for your CPU was included in kernel version 4.10
Based on this I would recommend installing a version 4.10 (or later) kernelas outlined below:
Issue the commands
apt-cache search linux-image | grep 4.10
sudo apt-get install linux-image-your_version_choice
sudo apt-get install linux-image-extra-your_version_choice
Edit: Based on the error "/usr/lib/nvidia-375/libEGL.so.1 is not a symbolic link" You also appear to be affected by this bug I recommend notifying the devs that it affects you too and subscribing to it so that you can be notified of progress.
A workaround has been reported here and confirmed here for that issue. The suggested driver is available here.
It would likely be prudent to completely purge existing nvidia drivers prior to installation (of 378.13) as described here.
As it seems there are some possible concerns I always recommend having a current backup so that you can easily revert to previous conditions.
For what is hopefully the final piece of the puzzle, I think we need to upgrade the entire Intel graphics stack as there is increased support for Kaby Lake CPU's and a number of related bug fixes
To accomplish this we need to download the Intel Graphics Update Tool which is available for both 32-bit and 64-bit versions of Ubuntu 16.04 here.
Install the deb package you downloaded with the Software Center (or your favorite package manager).
After installation launch the Intel graphics tool from the dash, and follow the prompts to install the latest graphics stack for your system. Assuming an error free installation, reboot the system to make the new driver take effect. (In the unlikely event something went wrong with this process we have our aforementioned current backup to restore and can try again armed with the knowledge gained from the previous attempt)
Note: If we want Ubuntu to trust future updates from the Intel repository, we have to issue the following command via the terminal.
wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-4 -O - | sudo apt-key add -
to install the key.
