Windows 7: Case Fans Continue To Run After Shutdown

Case Fans Continue To Run After Shutdown

I'm having a problem with one of my old computers and was wondering if anyone could take a guess as what could be causing it. This computer ran XP and several early builds of Windows 7 and Windows 7 home premium all smoothly but for the last few weeks the case fans will just keep running after shutdown. And I mean they will run all night if you let them, not just for a while to cool things down.

I'm not sure if this is even a windows problem or maybe more of a hardware problem. Could it be that maybe a power supply or motherboard may be going bad?

Thanks

are the fans connected directly to the mobo ,or through molex adaptors to the power supply?

Perhaps you could also try swapping a spare power supply with the one in your rig and see if the problem continues.

Hope this helps

The fans are connected through molex adapter's to the power supply. Unfortunately I don't have a spare power supply right now to try swapping it out.

somehow power is getting through the 12v supply line when switched off ,are you able to test using a multimeter? do you feel competent enough to remove the cover off the power supply and check inside ?
