  fans take longer to stop!

Hello to all!

I am fixing this computer, basic reformatting and reinstalling. Everything works ok except the fans (cpu, powersupply, case) take like a couple of minutes to stop. Windows shuts down, screen gets dark... fans just keep spinning for a couple of minutes, then they shut down.

Not a big deal, I guess. Do not want to bother changing the p/s but what do you think is going on here? the mobo? the p/s? the ...?

thanks in advance, Juan.

Whoa that's something I've never read before. Have you tried chekcing that there isn't a halt state set in the BIOS. I honestly can' think of anything else right now :s

Remember that just because the screen goes dark doesn't mean software isn't still running. It just means the screen was shutdown as just one part of the overall shutdown process.

The point here being to use something other than Windows to establish the system state and then shutdown...

Instead of booting all the way to Windows, enter BIOS Settings menu, and then shutdown the computer using front-panel switch. Might just reboot instead of turning-off however...depends on motherboard. There might also be a specific shutdown option to exit BIOS Settings menu and shutdown the computer instead of re-booting.

And/or boot using a freeware LiveOS such as Ubuntu or Knoppix, or some diagnostic (UBCD) or partition manager (PartedMagic) disc and use its shutdown option.

Depending on if you see any differences, it will help isolate the problem to hardware or Windows.

Here try this,


click START ---> RUN ---> then type msconfig

when it comes up... click on the startup tab...

under this tab, these are the programs that starts up when your system boots (besides the necessary system stuff that wont be listed here).... uncheck everything... save and then reboot.. once up at the desktop... let sit for a few... then shutdown to see if it powers off immediately.. If it acts the same as before... then its not one of those startup programs.. BUT... if it shuts down immediately, then what I would do is enable each program and do the shutdown to see if you can narrow to a program that is taking a bit to allow the OS to shut the system completely.

Excellent idea, G.G.! But if msconfig doesn't catch it, you might try something that provides more granularity such as "autoruns" (part of the sysinternals tools suite download at Microsoft or at majorgeeks)
http://majorgeeks.com/Autoruns_d4686.html
http://majorgeeks.com/Sysinternals_Troubleshooting_Utilities_d5473.html

or "starter"
http://www.snapfiles.com/get/starter.html

There are processes/services/dlls that "start" that are not needed that do not show up in msconfig->Startup that might affect shutdown operations. Examples would be antivirus programs, some update services, backup services like "reflectservice.exe", etc. While you may not want to manually mess with individual processes and services unless you have some experience, these 2 programs will show you more of what exactly is going on in your system. For example, it may show you that while you thought you stopped the startup of all the processes involved with anti-malware programs one or more related anti-malware processes may still be operational because you had a scheduled operation pending or similar reason. Or, you may find a dll that isn't needed is attached (e.g. a print monitor for a specific printer that no longer exists).

You may have to go to add/remove programs to do some cleanup, and sometimes you'll find a "remove" operation isn't 100% effective.

Another program that will tell you more about what is happening in your system in real-time is "process explorer"...another program that like "autoruns" is part of the sysinternals pack from Microsoft.


Warning. Real-time user manipulation of services and processes can cause unpredictable system operation, including loss of data. If you don't have experience in this area it's best to limit using such tools for observation purposes only.

I know that on my PSU the fans are set to go for 2 minutes after shut down deliberately to extract any remaining hot air from inside the case. I don't know if it works, but it never struck me as a problem.

Wouldn't go messing with the system setups for something that doesn't seem to be an issue :(

Just a quick update:

the system keeps doing it but it also works flawlessly. So who cares if fans take a bit longer to stop?
