CentOS 7 freezes after boot

I was having issue with a new mouse and solved it by installing nvidia drivers through elrepo (using yum install kmod-nvidia-340xx). This caused my second monitor to stop being recognized and while searching for solutions I ended up ruing yum remove xorg-x11-glamor. I noticed in the output that some nvidia files were being removed too, so I ran yum install kmod-nvidia-340xx for a second time and it installed everything again.

When I boot up I have a terminal window that automatically opens. I can see the cursor flashing for about 10 seconds then it stops flashing so I'm assuming it's frozen. Input from my mouse and keyboard are not being picked up either. I'm stuck and don't know what to do.

I can boot into single user mode but I'm not sure what to do.
