Problem with RAM

I decided to upgrade my RAM to 8GB.
I've already replaced a few parts in my PC like GPU, Powersupplier and HDD, and I've done It without help so I decided to do it by myself. So I took out my old memory and tried to put in the new one and I opened only one of the "teeth" that holds the RAM because the other one is blocked my GPU. I tried the first socket, It didn't work. I tried the second one and I heard a loud click which i thought was a good one, but apparently It wasn't. Now neither the old or the new RAM doesn't work. Is there a need in a new motherboard?
Can somebody please explain what happened?
