Hi, im not sure if this is the right place to post this, so im sorry if it isn't..

My xbox has 3 red lighst of death, and when i switch the console on it has no noise to say its switched on, the fan does not come on. Ive even left the console on for 3-4 minutes but nothing gets hot .. Does anyone know why? it has had the x clamp done..

Im really lost in what to do, all it shows is 3 lights flashing..

Many Thanks
