    Windows 8.1 Shutdown Hangs


    Every now and then when I shut down my computer it will show "Restarting" for about 1-5 seconds (My pc is fast) and the display will shut off. But the computer will still be running, the HDD and all are running. I have to do a hard shutdown by holding the power button.

    I have found this in the event logger:

    "The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S5). This can result in reduced resume performance."

    Source: Kernel-Power

    I heard it having something to do with "fast startup" or "Quick Boot" I am unsure.

    Check post #4 in this thread:

    The system firmware has changed the processor's memory type range - Microsoft Community

    Good luck.

    BTW, I have IRST disabled in my BIOS and my BIOS sleep state is also S5.
