Power light comes on when I/O switch is thrown, nothing else happens.

So I just put this computer together and when I plugged it in and I turned on the PSU the power light came on the PC case before I even pushed it. When I push the power button (on the case) to turn it on nothing else happens. No fans spinning, no boot, no lights on MOBO.

This is weird because I have two other pc's built from mostly the same parts although the PSU is different and when I turn them on the power light does NOT come on until I power it up. Of course they are running the way they should.

I have a PSU tester and the PSU passed fine when I tested the 24 pin and the 8 pin 12v connectors.

Well it seems you may be close to something, I checked and they were correct, but I reseated them and hit the power button, when I did the thing powered up!

Now I have another funny quirk, when the PC is on the power light is off and when it is on the power light is off.
