Just built a computer, won't boot up

Here's a video on my pc build and spec below, but basically it boot up after I followed the rules, and I saw the massive thread saying what to do during that process. I made sure the cpu connector was on, plugged in, power supply on, tested different power cables, took out the video card, put memory stick into another slot, and the front I/O cables into the right prongs. All the parts are brand new, not in box. I would put stand offs on but it would make the motherboard not aligned with the I/O board on the back.
