Ok, i just got done modding my PSU wires and now when everythigns plugged back in, the computer will not turn on. The lights and everthing turn on for a half second when i hit the switch, but it does not fully power up. I did not mod the 20 pin ATX conenctor, but i did do the 4 pin one, and it is possible i switched the two yellow and or black ones. I didnt think the order made a diff cause id think they would me them diff colors if they did. Do you know a reason it will not boot up? thanks
