Open the following folder on your OS drive: C:\Program Files (x86)\ASRock Utility\A-Tuning
Once there find the folders Conf and _Conf. Open the Conf folder first. Again the full path is:
C:\Program Files (x86)\ASRock Utility\A-Tuning\Conf\
You might recognize the file names in this folder as the names of ASRock boards. Your board's file is near the bottom, named Z87P3.
You can actually look at that file since it is XML code, used by Internet browsers. Double clicking it (in Windows 8) will open IE and show the file's contents. Don't change it, no need to do so, just verifying it exists and is Ok. It should have many lines in it, scrolling down quite a while.
If the files are there and yours is not empty, then something else is wrong and we'll take it from there.
