Hi guys, my pc is not turning on. Do you think my motherboard are dead? I check the RAM, CPU, PSU are.good. But my pc wont on. What should i do? Do you think its time to change the MOBO?

Have you replaced any parts recently? Also check the Power_SW header is connected up properly

What are your pc's specs including make and model of psu? How have you checked the cpu, ram and psu, in another pc? Has this just happened out of the blue or have there been issues previously?
