When Windows 8 is shutting down, it won't turn power completely off. The HD-led is lighting allthough the power-led has turned off. If I then press powerbutton, nothing happens. I have to take power-cable out of the wallsocket, wait about 20 seconds until the HD-led turns off. After that I can again turn my PC on as normal.
Booting into Windows 7, and letting it shut down, it works normally.
Is this a driver issue with my mobo? (ASUS P7P55D-E) Any ideas how to solve it?
