nvidia-304 304.117-0ubuntu1: nvidia-304 kernel module failed to build

[GGBerry]

I have an HP Envy 15j which caused me issues from day one with audio, video and wifi.

I was following instruction form a post in ubuntu forums to install kernel 3.14, which is supposed to help with the wifi issue (slow, unstable connection). My video and audio issues were fixed already.
At reboot, I got a popup for a system error, for which that report is.
