MB : Asus Z91-A
OS: Win8.1 with latest updates

Randomly, when shutting down, the OS shuts down but the PC fans keeps spinning. I got to turn OFF the power from the wall outlet to shut it down completely.

Is this a hardware or software related issue?

This PC is running OK, otherwise.

some fans do keep spinning for x amount of time, to keep cooling the system down.
Do they eventually shut down ?

Otherwise, likely to be a motherboard bug, assuming fans are connected to mb. Try a bios update.
Or Win may not be shutting down, just going into hybernate or sleep mode

No. I have to turn it OFF from the wall outlet.

All my fans are connected to the MB. Just updated my BIOS to 2801 from 2401 , few minutes ago.

It was working just fine until recently - it has happened 3 times already within a month.

In event viewer, there are a few critical errors almost everyday :

" The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding,
crashed, or lost power unexpectedly."

I am the only person using this PC and I DO shut down my PC properly; and my PC doesn't shut down or lost power 'unexpectedly' as reported by Event Viewer.

It sounds weird. The report doesn't look like its from my machine!

Dont have any W8.1's here. But on teh start page, type in Reli you are looking for Reliability Monitor / History, open that ( takes a minute or two to open). Its a lot more detailed, and should have errors when it shuts down with warnings etc. Click on a time and see what they report has faulted -- Hopefully its not one of MS's really helpful messages saying "your computer shut down" No damn kidding ;)

Yup, there are errors (almost everyday!):

" Summary: Windows was not properly shut down",

Technical details:
"The previous system shutdown at 10:09:17 a.m. on ‎2/‎02/‎2016 was unexpected."

Just took a closer look at the Reliability History, that, it reports Windows was not properly shut down when I shut down the PC (Properly); but when I restart the PC, there's no such report.

In short, the error is only for Shut Downs but not for Restarts.

I was wrong. Just did a few Restarts and Shut Downs, no errors reported. The last error was at 10.06pm when I shut it down.
