Questions about driver software.

Hello, I was wondering about if there were any driver updating software that is

**-not adware

-for linux ** I am in a big predicament concerning this laptop i've had for awhile. one day the keyboard just stopped working, i've finally decided to check it again an here are some notes.

**-the ribbon is clean

-some keys do work, but they all press shift?

-the "j" key when pressed lights up the internet key??

-when said working keys are pressed, they constantly press the shift key and I have to restart the computer to get it to stop. **

I presume that it's the drivers being really corrupted? so TL:DR where can I find a driver troubleshooter/driver updating software. thank you for your time!
