hello guys. are u having pc shut down issues? i also had that problem and i think i have a solution its working for me and m very happy to share it with you. a year ago my pc had an issue after i shut down the fans wont stop. i had to cut power from the plug manually. sometimes after gaming when i shut down the fan speed boosts very high and remain until i cut power manually. lately i plugged in a hard drive to the front usb port near the power switch. (please note that some casings may not have usb port near power switch) then after i shut down the fans boosted. i removed the usb hard from the port and the pc fully shut down. so i repeated it several times and it works. then i tried a different method. i kept my joypad or a pen drive plugged in while i shut down and it also works. so seems like its a usb port or power switch issue after all.
