    Fans still running after shutdown of windows 8


    'm running into a really annoying issue after upgrading from Windows 7 to Windows 8.
    I first noticed it during the initial (clean) install; when the installer tried to reboot, my machine (an acer aspire 4755G) just hung after the initial shutdown. That is, after the screen turns off, the power lights and fans are still running, and the machine itself doesn't restart. (I let it sit for a good 15 minutes, and it still didn't change)
    I managed to do a hard reset (power button for 5 seconds) and the install finished, but every shutdown/restart has been like that. Interestingly enough, hibernate works just fine.
    I've looked at other solutions where it said to use the "bcdedit /set disabledynamictick yes" command, and that didn't work.
    I also turned off the "Fast Boot" option in the power settings menu. That didn't work either.

    So far, the only option is to do the hard shut down by holding down the power button, but that proves to be horribly inconvenient.
    I've also updated all my drivers to the proprietary onces given by Acer, yet this problem still persists! It worked fine on Windows 7, so I'm not sure what went wrong here.

    Any help is appreciated!

    Try: sfc /scannow,to repair the contents of the Dllcache directory.

    It might be the problem from the installation, something might have went wrong. I would recommend you to perform clean install and let it install on its own (i.e no interfere), If the above code doesn't work.

    Hey SIL3NTKOD3R, I've tried what you suggested and Windows told me I have a 100% verified install. I'm going to try and a clean install and I'll have an update on what happens.

    Do you have any other suggestions if the clean install doesn't work?

    Try clean install, if that doesn't work im sure we can figure out a way to fix the issue. Let me know how it goes.

    Alright, clean install finished, and my restart/shutdown problem is still there.

    I find it weird, how I'm able to sleep/hibernate though.

    I've got the same problem.

    Disabledynamictick doesn't help.
    Turning off fast boot doesn't help.
    Redownloading and doing a fresh install of windows 8 doesn't help.

    What I'm struggling with is any way of monitoring what's actually happening at shutdown.

    Glad to know that I'm not the only one with this problem, and yeah I'm having trouble finding a way to find out what's actually going on as well.

    JPR, just wondering what setup you have running Windows 8?

    Hi docaholic, can you check your min/max power states while "plugged in" of your CPU in Advanced Power options. It's an out side chance but worth a try.
