So my pc wasn't turning on so I decided to try and clear the cmos with the button on the board and by the battery but that didn't work, so I took out my psu and tried the paper clip method it worked my psu turned on so it wasn't that. Just in case my psu was the problem I changed it with another spare 600 Watt one it worked on my other motherboard but not on mine. So then my cousin comes in bangs the pc a little and hit the power button and it turned on! Problem now is I put my case back together so I could play on it and now it doesn't turn on again! Bull crap so at this point I tried taking out the video card, ram one by one, wireless card, nothing. I bench tested it nothing works. But just a few minutes before all of this it worked. My pc worked a few days ago perfectly , I change my room around and now this. Please someone I need your help this pc is my life! I tried to jump the 2 power switch pins with a screw driver it won't work, cleaned the ram tried different slots it still won't work. I have no idea why this pc won't turn on!

My pc has been running fine for months now nothing, I noticed if I do the paper clip method to my psu while the 20 pin is in the board the board turns on but once I take the clip off the 20 pin the board shuts off
