I am on Windows 8.1, I was in Windows 10 but it has too many driver issues and stuff so I factory restored, and still this event happens. Have the latest BIOS: BIOS Version/Date Insyde F.42, 18/03/2015 SMBIOS Version 2.8 I had to factory restore again an hour ago since the factory restore wasn't a full one.
