    If this like my problem issue.. Your cassing screw (behind your motherboard) has connected with 4 pin motherboard slot. So unscrew that and move to another screw hole , and I hope your problem will be solved

      Hey dude help me too I'm facing same problem and my board is also out of the casing what to do?

    You have a short in +12V circuit (close to EPS plug). It could be broken diode or transistor (MOSFET). PSU not start because safety system detects a short in the EPS plug. It prevents PSU from starting with short +12V rail and burning PSU.

      @Rafael Brandão If you have the same problem, then motherboad is broken not PSU.

    eazy test put in 24pin and 4 pin switch on, if the fan turns on the cpu does not get hot. its one of the little black mosfets u need to checkor replace.if the board receives power its defently the 12v rail to power the cpu. i have same issue , found the mosfet , but have not got a new one yet, less priority for me

      We have the same problem.. try to troubleshoot try to change ram, CPU, Graphics card maybe one of them will fix your PC. If it didn't fix or solve the issue try to change your Power supply
