    Yea...so we finally got my girlfriends new PC up and running. The problem im having...or more of a concern really. Is when you flip off the power supply, and then flip it back on, the PC gets a short burst of power. IE the lights and fans all come on for a second or two. Then you can press the power button and turn it back on.

    Any ideas guys?

    yea some computers do that, when you plus the power cord in, the electric current has to get into the mobo, kinda like a pre-warm up

    That's normal behavior on some power supplys and boards. You really shouldn't need to turn the power supply off at the unit, let the machine shut down the power supply when you shut down windows.

    Yes that is normal on many systems. One of the reasons for the behavior to allow for Wake-On/Power-On functions of the board.
