I have a Dell that's a little over 2 years old. The boot HD failed so I replaced it w/a new HD and reinstalled Windows 7. The system boots and runs w/out any problems. However when I shut the system down it powers off then starts to power back on for 1-2 seconds then powers down. It continues to do this until I unplug the power supply. When I plug the power cord back in it doesn't exhibit this behavior. I've checked all the BIOS settings and reinstalled the OS. I haven't installed anything new except the HD.
Has anyone seen anything like this? Could this be a PS problem? I would hate to think that it's a MoBo problem.
