Remember, DriverPack 12 was released around 2012. Its database does not contain drivers for hardware released after that date (like 8th Gen Intel processors or modern NVIDIA cards). There is no "fix" for this. If you are fixing a modern PC, you must use the latest version (DriverPack 17 or newer). Only use Version 12 for legacy computers (Core 2 Duo, first-gen i3/i5/i7, etc.).
