GA-Z97P-D3 doesnt turn off

[pcpro]

I had some strange things occuring with this MB.
Some is solved , but still the MB doesnt turn off, when I turn off Windows.
It looks normal at the screen, turning off screen turns black.
But the computer still spins, seems like MB doesnt get a turn off signal for the power.
What can be the problem ? A setting ?

Actually, I thing its the Cosair water cooling that migh delay complete shut off.
Because it shuts off after like 5 minutes.
But I dont know if there are any settings for this, or indicators.

If this install was migrated from another system (motherboard) and a fresh install of windows was not performed, this could be related to the behavior.

Have you tried Disabling Fast Start Up in Power options?
