DVI No Signal after switching pc cases

[ITouchMyself]

So my pc was working fine and then my new NZXT Phantom 530 arrived. I took my current pc (an asus m11bb from best buy that I bought in 2011 but it has a GTX 960 now and a 500w psu) and moved it into my new case. Everything works when I turn it on and the fans spin and everything. I plug in my monitor (about 4 months old) and get DVI no signal. I was confused and tried my other gpu port and it didn't work either. I then took out my 960 and tried to use my mother board's default DVI port but that didn't work either. I tried switching out and around my ram which didn't change anything and I plugged in my headphones (I heard somewhere that you are supposed to hear beeping when it turns on or something) and I didn't hear any sounds at all, not even the usual static I hear. I then tried using my old monitor (a TV that used hdmi) and that didn't even display either. I never dinged or damaged my motherboard in any way shape or form while transferring it or putting it in. I have tried unplugging everything and plugging it back it but that also was to no avail. Please help, I'm out of options and it was just working right before I did the case swap.

Are all the power connectors connected like power connector to gpu, 4 pin for the cpu
