followed your video instructions to download and copy noobs to my sd card. nothing happens after i insert sd card, plug it in and power it up. am i missing a step? the start up screen does not happen like it does in your video.
Have you taken a look at our troubleshooting forum post for Raspberry Pi?
Make sure you’ve followed all those steps, including using a high quality card. Perhaps try a different SD card or a different OS image.
