I have just built my first PC, it will post and it reaches the BIOS but when I try to boot from the USB I get no signal on my monitor. I can only get back to the BIOS by pressing the mem ok button on the motherboard. The USB drive is first in boot priority, I've also tried booting from the boot override screen.

I'm trying to install windows 7 x64 I have ran the iso through ISO to USB.
