Carefully follow all the steps here: http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems
(additionally check using onboard video if you have it, vs using discrete graphics card). I watched your video and the only "mistake" I see is using the bottom PCI-E slot - that one is often x8 or x4 speed only, but shouldn't cause a no-boot, just might be slower. Use the highest PCI-E slot first. Take everything apart and reconnect it all if you can't get it to work, that can fix issues with a bad connection/connection just barely not correct.
