The last time this card wasnt working for another user it was simply because windoze was not fully shut down.
And this was on a machine where windoze was not even still installed!
Please advise if you are dual-booting, windoze was previously installed, and/or are familiar with whether ‘Fast Startup’ was disabled and/or it was fully shut down.
( In that case the user succeeded by fully removing all power supply for some minutes )
