What should I do if the error persists after reinstalling the drivers and rebuilding with DKMS?

Check your system logs (e.g., `/var/log/syslog`, `/var/log/kern.log`) for more detailed error messages. Ensure your kernel is up-to-date. Consider trying a different NVIDIA driver version. If you've recently upgraded your kernel, it's possible the driver is incompatible and needs to be updated. Finally, search online forums and communities specific to your Linux distribution and NVIDIA GPU for solutions related to your specific configuration.
