So my computer randomly shut off while I was using it. When I tried to turn it on again my keyboard mouse and monitor would not turn on, yet my computer was on, all the leds and fans were spinning. I know it is not my motherboard though, or at least I do not think so because my headphones were also plugged in and they turned on. I also tried removing my RAM, still did not work. Could it be my PSU? My video card is not the problem either btw.
