My keyboard is so messed up?

I could really use some help! My keyboard on my Lenovo laptop started going crazy such as letters like S, Z, X W CRTl Fn and basically most of the left side
From what I can see this is what happens
S = as (these are what happens when pushing the button)
X = zx
Ctrl = '
And much more but is there a fix to this?
(I'm using an on screen touch keyboard to get this typed)
