Computer not turning on with modified case mod

Hi, I am improving on my case mod here and I have ran into an issue. My flip and key switch works fine with my wall plug that I am using but does not turn on my computer while using an updated version of it. My new version is using a usb plug to power it (which will be plugged into a usb port). I have thoroughly tested the voltage and current in the circuit and it is the same as with the wall plug. I made a LED circuit on a breadboard to test the wall plug and usb which resulted in identical results of lighting the usb. So from this I know that the plug and the usb both perform the exact same (5V, 20mA to the optocoupler that I am using). I have tried plugging the usb into a different computer but it still did not work. I know that the voltage isn't a problem because this has been running 5V from the wall plug, and the 500mA cap on usb power is not an issue because I am not even using 50mA of power. If anyone happens to have a good idea of what the issue is, please do respond! Thanks!

I made this in the troubleshooting section because I am trying to troubleshoot this problem in order to fix it (not case modding right now).

 

Edit: Pictures are sideways for some reason, not sure why.

The optocoupler is a PC817

I wasn't sure if it was a logic issue because the optocoupler must stay powered long enough for the motherboard pins to short which in result turns on the computer. I didn't know if if there was something special with usb and power that I was not aware of either.

check to make sure no exposed solder or wires are touching where they shouldn't be and if thats the problem just run down to the local hardware store and pickup some electrical tape
