cpu fan keeps running after pc is shut down

[ssk_the_gr8]

it has been happenin for the past few days..
after i shut down my pc.the fans in my cpu keeep running.. i opened the cabinet & checked.. the red H.D.D light keeps flickering .. & i cant switch on my pc again..
even if i switch of my UPS & switch it on again.. the fans inside start up again & the red H.D.D light keeps flickering.. i cant switch on my pc.. so i tilt my cabinet & do stuff like that.. & somehow if the red light goes off & fans stop then i can switch on my pc

is this a connection or wiring problem? what to do?

Its mobo problem. Get it checked carefully thru power cables.
