Dear sir,

Motherboard:  2Ghz intel procesor, 256 MB RAM,  XP
after purchasing the pc it done good job,
but at last week one problem will occur.
when we give the shutdown normally in the P4 we don't push the cpu button after shutdown but since last week when we give the shut down we have to press the cpu switch for proper shutdown .Generally in P4 at least click on Turn off ,then we have to close only main switch.But in my computer I have to puss the butten of CPU after turn off.

please give me the reply,

Your best regard.
