It looks like something might be connected wrong. Double check all of your front panel connections - power button, power LED, drive LED, reset button etc.

 

If it's still happening, disconnect all of the front panel connectors, with the exception of the power button connector and try again.

If it works fine, you can start connecting other things back and trying it, one by one.

If you still have the same problem, disconnect the power button to see if the same thing still happens with none of the front panel connected. If yes, then your problem is deeper.

so it seems the problem is deeper  .because i already tried it with the front panel connectors

Ok, at this point you can double check all of the power connections both on the power supply and the motherboard.

You can also try disconnecting all the power cables from the power supply itself (leave the main power in connected), then flip the switch on the power supply, if you hear any clicking from the power supply itself with everything disconnected then it has a fault and needs to be replaced.

 

If you don't hear anything it could still be the power supply or a problem with the motherboard, either way testing it further will require replacement parts.
