Upgrade and Centos errors

It seems that during my recent upgrade to sng7 my system has stopped. Currently I can not activate my system and the latest version of the kernel hangs on reboot.

rpm -q kernel
kernel-3.10.0-693.11.6.el7.x86_64 (This is the one that hangs)

Should I remove that kernel to see if I can still upgrade my system, or will that do more damage?

Please advise.
