Please create a new nvidia-bug-report.log after you booted with the nvidia driver installed, possibly from recovery mode.

sorry for the late reply

Not looking good:

[    7.205673] NVRM: Xid (PCI:0000:01:00): 62, pid=1036, 0000(0000) 00000000 00000000
[   15.376544] NVRM: Xid (PCI:0000:01:00): 8, pid=932, Channel 00000008
[   48.173107] NVRM: GPU 0000:01:00.0: RmInitAdapter failed! (0x26:0xffff:1290)

as soon as it’s throttling up, the gpu is crashing. Please

  • update bios
  • reseat card in its slot and reseat power connectors

If that doesn’t help, please check if it works in another system, otherwise have it replaced by vendor, broken.

ok, anyway, thanks for the suggestions.
