I have had this problem for years and thought it was a bad card.
Replaced it recently, still have the problem.
The issue with nvidia's driver is that it doesn't play well with CSM
enabled in the BIOS. If you have the option to disable CSM, then it
should work.
CSM is the "Compatibility Support Module" of UEFI. With it enabled, the
graphics card is initialized by CSM, not by UEFI, and that it not fully
supported by nvidia. If you use UEFI with the EFI console driver but
still get this in dmesg:
NVRM: Your system is not currently configured to drive a VGA console
NVRM: on the primary VGA device. The NVIDIA Linux graphics driver
NVRM: requires the use of a text-mode VGA console. Use of other console
NVRM: drivers including, but not limited to, vesafb, may result in
NVRM: corruption and stability problems, and is not supported.
then the issue is that you have CSM enabled. Unfortunately, some
mainboards do not provide an option to disable CSM.
