Problem: Asrock Intel Series Z68 Pro3 Gen3 can't instal graphic's driver
Driver found on original Asrock Cd or Asrock Web page didn't help, there is an error message "minimum requirements". Windows Update found driver and instal it without problem.
Unknown device (ACPI properties) can't be instaled - workaround is disabling option in BIOS:
Advanced - Intel(R) Smart Connect Technology - Disable it.
