Are you using Mate or Cinnamon?
Can you run uname -a in a terminal and copy/paste the output?
Linux Mint
There should be a teensy bit more info than that, fren...
Something along the lines of:
Linux expandedAnus 5.4.0-89-generic #100-Ubuntu SMP Fri Sep 24 10:50:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
I think mint has neofetch in as standard, so if you could run neofetch in a terminal and copy/past the output of that as well, it would help.
Ubuntu. I know very little about computers.
I found this
