I'm completely out of my depth here, apologies if I'm being redundant: Had the same problem. Found a driver from MS catalog that works on my system, Win 8.1 x64, Intel g4560, ASRock H110M-DGS. Here are the catalog links:

Other catalog drivers would not work.
Had to disable driver signing check and then installed it by right-clicking and running the .inf file, which installed the entire setup with the Intel control panel. If this solves your problem or helps in some way, please let me know and disseminate.
