Yes, chuck it in the bin and buy a new one, unless you have a circuit diagram for it or the patience of a saint to repair it, don't bother.
i did that really but that fault occurs more and more in other PSs, i thing it could be a simple fault .
Would you please tell me if you have an idea about the element caused this fault

Connect a 10Ω, 10W resistor across the +5V output and try again. This prevents the 5V supply going too high and tripping the overvoltage circuit.
