Error message on boot; ERROR: Can't start miner, unable to get number of CUDA devices, is nvidia driver installed?

Hi, I just re-installed hiveos on a usb, inserted all the info. from my account which i already have setup with all the infos, into the rig.conf file on the usb and rebooted the OS.
First message on boot was there is no driver installed for nvidia. installed the most recent *440 and did a reboot.

Now on the reboot i’m getting this message when i start the miner;

"Skipping miner log rotation due to execution time < 30sec

20200806 19:21:55 ERROR: Can’t start miner, unable to get number of CUDA devices, is nvidia driver installed?
20200806 19:21:56 T-Rex finished

t-rex exited, waiting to cooldown a bit

Also when i input the command; nvidia-smi , it says there is no nvidia driver installed.

I’ve also tried purging everything nvidia and reinstalling the nvidia driver that way, and still nothing shows up under nvidia-smi

And when i try to mine, it says; “Detected 1 NVIDIA cards
No cards available for OC!
Please check BIOS settings, risers, connectors and PSU.
Try to update Nvidia drivers.
ERROR: NVIDIA OC failed”

I need help with this please
