If Elive 3.0.3 worked that's an important information... what changed? hum...
Can you try to boot with the "debug" boot option (menu)? and put here a screenshot of the last messages in the screen
Which tool you used to record the USB ?
Can you try with a different USB too ? (but if worked this one with 3.0.3 it should work too...)
That's strange, I'm not able to reproduce the issue here with 2 similar computers where I tried the USB version 
Have you verified the MD5 ? but if you downloaded it again it should be correct, hum...
