My husbands computer has a an AMD hd7700 MSI video card. The options for the fan in the overdrive section keep suddenly disappearing. He's using the AU version of windows 10 home and the lates drivers have been uninstalled with DDU and reinstalled. Fan options were previously there and working with this driver set. Would like some idea's on this issue as all the searches I've done have brought up out of date answers where fixes have already been introduced to the previous driver software.
