its one thing of many to check.

make sure all cables are plugged in right... (especially the front power button on the case, if thats not connected right, it won't power on, but one can take a flat head screw driver & short out the two power on pins on the mobo to trigger it to start or reboot if needed, to test to make sure it fires up.)

make sure there's no motherboard standoff's in the case not where their supposed to be... its possible even one standoff on the motherboard tray, could short out the back of the board & cause it not to reboot, make sure there are only ones located at each of the motherboards mounting holes, no where else.

test the system with 1 stick of RAM, then the other, its also possible one stick could be bad, or both could be, also resulting in no boot up.

the hissing sound your referring to, could in fact be the PSU, but it could also be the PSU/Mobo "filling up" with juice, normally when you disconnect a previously powered mobo from the psu, or disconnect the PSU from the wall plug, the PSU/Mobo will make a short hiss sound as the excess power cycles out of it. sometimes firing up a PSU or plugging it in, will do the same thing.

there's a lot of different sources for the problem, its just a matter of pin pointing it, just need to be patient & think it all out & more or less trial & error methods of figuring it out.

There are no extra standoffs. I tested the system individually with each stick of RAM.

The hissing sound only occurs when I have the system plugged in, it is flipped on, and I am holding the power button on the case.

I think I'm going to go insane!! I really hope I am missing something but I just don't know what it could be..
