Helping my wife cousin computer problem. The symptom is the computer will power ON for 1 second then off, no beep. 1. I have tried another power supply and had the same issue. 2. Remove memory and SSD and had the same issue 3. There is no light on the motherboard that indicate power is fed. My understand is all motherboard make and model have light on the motherboard that indicate power is connected, I cannot see such light. I think the motherboard is dead and I would like a second opinion.
