I'd try with MHWD (either chrooting or booting to a TTY).
Assuming (from your previous topics) you had a Nvidia card, I'd try:
sudo mhwd -r pci video-nvidia-dkms
sudo mhwd -i pci video-linux
Before the first command, maybe you'd better check what you have installed with
mhwd -li
To remove everything Nvidia-related.
