DVI, HDMI, PS/2 ports don't work. USB does?

So let me give you a brief. I built my computer about a week ago and it has been fine. I was doing some cable management and one thing lead to another and the system switched off (Noob move, shoulda turned it off) However when I switched it back on, none of the ports work. When I tried to switch the system back on my television said "No Signal". My keyboard also posted showing no life. After many different attempts of checking everything was plugged in correctly there is no change. I have now taken the board out of the case and replugged everything and there is no change. The only things connected is the cpu, ram, power and led cables to switch on, ram and the video card (Tried with and without). I have tried my hdmi cable in both the mobo and the gpu but both give the same results. I am struggling to see what the problem is. Any help? Parts listed below

    The thing is, is that the motherboard was alright pre this accident. But now it seems as if everything has gone out the window.

    Yea, you could've mucked up the bios, I reckon you should trade it in and get another one back.

    I didn't change any of the bios though that's the thing. I think I'm going to buy a usb to hdmi adaptor so I can at least get a visual.
