Computer doesn't automatically turn off after shut down

Windows shuts down fine but I have to press and hold the power button to turn it off (the fans etc.).

I'm pretty sure this only started to happen when I changed my computer cases. Not sure if something like this can cause the issue.

Also, something else that may be related: When I restart, my PC shuts down, turns off for a few seconds (inc. fans), then powers back up.

Any ideas?
 
Did you have Windows 8 installed when the machine was in the old case? I'm wondering if Windows 8 quick boot has gone amok.
 
Good chance it is not a Windows 8 thing. My rig does the same thing (always shuts down completely when restarting, intermittently does not shut down fully when doing a shutdown) and I have only ever had Windows 7 installed. I also have an ASRock motherboard, a Z77 Extreme4.

I also don't believe it's a Windows thing (but I could be wrong). If you're having the same issue with a motherboard of the same make, I wonder if it's a motherboard setting/bug?
 
I am actually a fellow owner of the H77M. That second behavior you mention does happen when you tweak and save certain BIOS settings, but I don't think it happens when you do a typical reboot. I might be able to try it out tomorrow and see what happens. Since I never noticed that behavior, I think that it is NOT supposed to happen.

I don't believe it's supposed to happen, but I'm unsure what I could have done in the BIOS to cause this :S
 
My systems all power down running this command:

%windir%\System32\shutdown.exe -s -f -t 00

Nope...... Im on Win98se and the same thing occurs.....

I notice if i shut down w/o having loaded too many drivers in memory (Opening alot of programs) it will shut down correctly... Otherwise I have to hold the button!


I dunno if adding "Always unload dll" (and setting the value to 1) to my registry would correct this or not,i guess i could try it right?

This works on all OS's i assume... (Windows OS)

If this is the reason for the improper shutdown,seems like the computer doesnt unload the files correctly @ shutdown and stalls??

I don't know if this helps, but I had a similar issue with restarts. My computer would shut down okay, but hang preBIOS on soft restarts. I'm pretty sure it stopped when I upgraded my video driver.
 
Had this before too, pretty sure it was an ACPI thing.

I'd check for motherboard drivers (or BIOS's) from manufacturer's webby.
 
Just to clarify there are two different types of shut down problems being discussed in this thread. One where windows doesnt shut down all the way, and one where windows does shut down but the computer simply does not shut off. If windows doesnt shut down all the way then the monitor will stay on. If windows does shut down properly then the monitor will turn off. I've seen both types of problems on multiple machines. The 2nd type of problem is probably bios related. I changed every acpi setting I could and never did figure it out. I ended up disabling acpi, which forces windows to display a message like this:

No. I'm pretty sure the only issue in this thread is with ACPI drivers. There is perhaps a tiny chance it's a BIOS issue.

There is no point disabling ACPI. The solution is, most likely, to correctly install all motherboard drivers directly from the manufacturer.
 
most important question.

Are u on stock or overclocked settings?
 
In Windows 7 go into Device Manager and the the IEEE1394 Bus Controller. Right click the controller and go to the "Power Management" tab.
Check-mark "Allow the computer to turn off this device to save power"
Your computer should shut down completely now.
