i built a computer 2 days ago:
Intel 3570
gigabyte z77x-ud5h
Samsung 128 ssd
corsair 2x4 gb sticks
(i also have 2x2gb g,skill rams but im not using them at the moment)
nvidia 770 gtx


i dont have a DVD reader on my computer so i have been trying to install windows through a usb.(i have a key for the windows so lets get that out of the way). i downloaded 3 different windows 7 home premiums from different websites because every time i try and install any one of them i get "Error code: 0x80070570".
if anyone has any suggestions on what i can do it would really help me.
