Hey Fshamk

Have you checked that wake on lan is disabled in the bios? Is there anything in the event viewer to perhaps shed more light?

Does it do the same thing when going into Safe Mode? If it doesn't then you have some application/service that is overriding the power-off command.

Also, what happens if you just do a shutdown /s /f /t 1

Turn off the Power to the machine (unplug it from the wall). wait 15 seconds, turn the power back on.
Start the machine.

Virus or Corrupt Power Sequence?

by keybonesabi In reply to windows 7 won't shutdown ...

Earlier versions of Windows were infected with a virus. Easiest way to ensure it's not your hardware is boot with a known clean device (CD, USB, 2.5" <-ha ha).
Other forums suggest it is a conflict between Windows Power Management and BIOS Power Management.

I'd start with scanning for a root kit once you have determined it is not hardware.

maybe it is the power switch

by Sue T In reply to windows 7 won't shutdown ...

I had this happen once and it turned out to be that the power switch was bad. I replaced that and the problem went away. Is your switch sticking at all?
