My PC's fans don't turn off after shut down

December 28, 2010 at 21:15:06
Specs: Windows 7
my friend gave me his PC that he built. I upgraded it to Windows 7 from XP and ever since the upgrade the cooling fans will not shut off unless I hold the power button down after shut down. Any idea what is wrong.

It is not shutting down for some reason. Not sure if the system is still trying to work or some problem with acpi.

Why did it take me over a year to phone in a problem to ATT?

It may be that the power option was set to standby and not power off ??

When i do the Start> Shutdown that is when it will not shut down properly. If i hold the power button down then it completely shuts down.

Did you by chance go to a 64 bit version of Win 7?
I have maybe the same issue but I noticed on a system that I upgrade from XP to XP Pro 64 bit at first. When I shutdown the system shuts down but two fans ( one front and one rear) and the fan in the PSU as well as some pretty little case lights and the light in the mouse continue. I have to hold the power button for nine or ten seconds to shutdown completely. I thought I had damaged the power button because when I upgrade the OS I also pulled the box apart and cleaned it. I replaced the button and it did not help. This has been like this for three years now. I did go back to XP home once and that solved the problem. This is what lead me to believe it may have something to do with a 64 bit OS. I am now running Win7 Ultimate on that system and the issue persists.

Oh boy......yes, yes,yes. Exact same issue. I went from XP Pro to Win 7 ulimate (64 bit) . SO I am guessing it is something with the upgrade. So what do we do now :-)

I have been trying for three years and have not yet found a resoulution. Before anyone asks yes I have been through all the power settings.

Surely someone else has had this issue. Anyway, I'll keep looking around. Initially i thought maybe my bios settings were off .
