Order of updating. Preferably on a clean install.
1. Bios
2. OS
3. Chipset Drivers
4. Intel Management Engine Software Driver
5. MEupdatetool (Note: This tool is not the same as #4 above. It is to patch/update a exploitation in the bios firmware and Intel Management Engine Software. If your bios is newer than the MEupdatetool, then don't use the MEupdatetool. Otherwise it's up to you.)
6. All other necessary software drivers (Video, Audio, LAN, Wireless....etc.)
