S key is not working

as of two weeks ago my S key was not working (i am on a different computer right now). I got the tip of going into safe mode, not knowing what to do next i tried typing in safemode and it worked perfectly fine
when i went back to normal mode it stopped. I have attemped to uninstall the drivers and they work fine until i restart my computer as prompted

i do not know what to do, i am sick of copying and pasting S’s into all of my papers and conversations

help
