So i just swapped my motherboard, ram and processor and when i turned it on. It shut off In about 10 seconds and nothing shows up on the monitor.
Im wondering if this is my psu because it only has 430 watts and the processor is an i5 6600k and my graphics card is an gtx 750 ti. And im also wondering if the issue is caused because i do not have any new thermal paste under my fan.
