I just got a new NF7-S from newegg and when I set it up it booted up fine 1 time. I accidentally barely kicked my desk and the power went off and I had to reset cmos to turn it back on, but when i turned it back on...it went to a black screen. My monitor doesn't change and the button does the same thing it does when the computer is off. I've tried switching video cards, setting the board on cardboard and booting, switching memory, but none have had any success. Is there anything else I can do?
