Hi Tomasz,
My gut instinct is to agree with Aron here and say this is likely a broken
card, most likely the memory. However, it would be useful to know what you
mean by half the tests fail. How do they fail exactly and what error
messages do you get. Do you have the log files, especially the diff log
from running the tests?
nvidia-smi -a
should show the card. I would try reinstalling the NVIDIA driver first
though and then powering off the machine and starting it up again. You
might want to also take a look inside and make sure nothing is stopping
the GPU fan spinning as well, I've had issues like that before with an
internal USB cable that wasn't secured being ingested by the GPU fan.
Try a reinstall of the drivers first and a cold power down / restart and
see if that helps. Run 'nvidia-smi' as root to get the driver loaded once
the machine comes back up. If the problem still persists then suspect the
hardware.
All the best
Ross
