When I shut down my PC through windows 7, all the fans, including the CPU fan, still run. Also, the motherboard still runs as well. Not sure where the problem is coming from. The way I shut it down is I wait an estimated amount of time it would take for it to shut down then I hold the power button to shut it down. If I don't do this, the computer will run forever if I let it. This never happened before until a few months ago. I thought it was fix itself eventually but it still persists. Any help is appreciated.
