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.
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.
