Re: S7-392-74508G25 motherboard problem

Since you have the Haswell-ULT version of the S7-392, you have to make sure you're using the Windows 8.1 Intel Management Engine Interface driver if you upgraded your computer to Windows 10.

If you're still using Windows 8.1, then please disregard my post.

Edit:

Or use the Windows 8 Intel Management Engine driver (ME driver)
