It crashes when gaming or any time? Could be bad power supply, bad video card, motherboard issue. Depend on exactly what happens and when. Did you check temps in the system? Is anything overclocked? Was anything tested/replaced already?

Hi, for now we fix the problem we just reconnect the ram and graphic card, clean the pc.
But thanks at all.
