Typing error can't fix (WIN10)

I'm using ASUS K450J Window 10

When I type "c" or "0', it will come up "c0"
When I type " shift+' ", it shows nothing first time, and then " "" " in the second time
When I insert " k " in a sentence, it shows up " k " and go to end of line
there are also other errors, but I think some of the keys become common key for more than one keys
It has troubled me for more than a months already, can anyone helps:'(
