Hello,

<snip>... the power supply the fan dont come on

If the PS fan doesn't come on (or spin?), then you need to check if the fan is frozen. Sometimes frozen fans will pull down the +12 volt line to where the computer will not boot. Don't depend on leds to tell you things might be ok. If the PS fan is bad, then you shouldn't be attempting to run the computer or you may cause more damage. If the PS is new, then consider RMA'ing it.
