Im not sure if its my PSU or what

[PrettyBoyDraven]

So my computer black screened and i flipped the switch on the back of my PSU, when i did that and tried to turn my computer back on it wouldn't come back on, the only thing it would do is light up my mouse, keyboard, the front light on my case,and move my CPU fan just a a little, this would only last about 1 second before everything turned off again, i pressed the power button and nothing would happen unless i unplugged my computer and then plugged it back in again, then it would only do the same thing, i looked on other forums and it said to take out the CMOS battery for 10 minutes then put it back and that did not work i am at a complete loss. thanks for your time

MERGED QUESTION
Question from PrettyBoyDraven : "I'm sure something is wrong with my CPU"

So i was in mid the middle of a game, and my screen when black. I flipped the switch on the back of my PSU and then flipped it back on and tried to turn on my computer it didnt come on. I made another post on this and i had some help. We found out it was when the CPU was plugged in the motherboard it wouldn't turn on. I unplugged the CPU and it turned on. does this mean the CPU is broken or something else?
