    Fan still spinning after "Shutdown"...

    Hi there -

    I'm having a strange issue with a new computer that I built and that's running Windows 8.1. When I try to Shut Down the computer, it looks like it's shutting down just fine, my monitor goes dark, and my hard disks spin down. BUT, the cooling fan keeps spinning. Any idea why it's doing that and how I can remedy the issue?

    FWIW, I have a Gigabyte GA-Z77X-UD5H motherboard.

    Thanks in advance for any suggestions/advice!

    Check the bios settings. Bios up to date on its Firmware? Anyone else on the Gigabyte forums having the same issue with that Motherboard and Windows 8? Looks like it has been a long ongoing issue since 2012.

    I would also double-check that every fan connector is connected the right way round. Some of them can be made to fit in more than one way.

    I'm experiencing the same problems, and while I haven't yet found a solution, some of those suggested are: "Check your power supply (connectors, dust, etc, replace if needed.) Check your processor, its fan, etc. (again, connectors, dust, etc, replace if needed) GPU? Keep checking.

    Look through your PC's hardware components, clean if needed, replace if absolutely necessary. (Bad power supply caused the same problem for a friend of mine years ago. But that was the 2000/XP days.)

    Currently, I'm running SFC and looking for corrupt files, such as those that control a proper shutdown. (Registry, anybody?)

    I'll let you know if I have any more suggestions.

    Try a different method of 'turning off' the computer to maybe narrow down the possibilities of this issue...
    1) try pressing the power button on the computer, so Windows would properly shut down. Still happening?
    2) start up the computer, then turn it off by holding down your power button for a few seconds. This will immediately turn off the computer without the shut down process. Does the fan still run? (Then maybe that could be your power supply)
    3) Let's try this. Let's turn on Hibernate, if it isn't already enabled on your computer:
    > To turn on Hibernation, open cmd.exe as an administrator and insert:
    powercfg.exe -h on
    (this creates: C:\hiberfil.sys)
    Now try to Hibernate your computer. Does the fan still run after it completely turns off your monitor & disks? Then power supply's having problems, I guess, like stated before?

    If you don't want Hibernate on:
    > To turn off Hibernation, open cmd.exe as an administrator and insert:
    powercfg.exe -h off
    (this deletes: C:\hiberfil.sys)
