Clicking noises are exactly what you hear when you overload or short a switching power supply ( the kind inside the SE). The supply tries to come up, sees a load that is too large, and protects itself by shutting down. Since you did not mention any hardware mods (or did you?), it sounds like something in the supply blew. A blown fuse on the 115 AC side cannot be the problem, since the machine would be silent in this case. However I don't know if the DC outputs of the supply are fused (I doubt it). If so, this could cause the symptoms, although I really don't know that much about switching supplies. Good luck. John Andrews
