Missing OS System long story

[veliz50]

So i kinda need help. i finally built my own pc 2 days ago. and it isn't working out well. so let me start from the beginning i built everything and started it up but since i don't have a cd reading thing i cant use disc, so i downloaded a windows 7 file onto a flash drive so it could install then i could use my code and activate it once it installed, but the first time i tried installing it it got stuck at completing installation so i reset it and tried to do it again but had no success it failed halfway through saying something about my drivers and such when i was choosing my installation location so i tried this ( https://www.youtube.com/watch?v=fo7tyFFjSsA&feature=gp-n ) after i got to the part where it said to format=ftns quick it just kept saying no volume, so i tried redoing it and my disk wouldn't show up on list disk anymore which was disk 0, so i ignored that and tried reinstalling and my driver or disk where i would install windows 7 wouldn't show up, and if it did windows would just say its not formatted or choose something in bios, i've tried everything and have spent the past 3 days trying to fix it. if anyone can help please let me know.. here's a list to my components ( http://pcpartpicker.com/p/Pnv8CJ ) please help.

Make sure your USB disk is in a USB2 port. When you boot, and go into advanced disk options, does it show the drive there? If it does, select it and create a new partition, then try to install on that. Is that the steps you are taking?

I would also replace the power supply. Seems like you got things based on price not quality, but a bad power supply when it fails can not only just fail, it can burn out your motherboard and CPU as well.
