Lenovo Idea Pad Number Keys activating multiple keys

Hi,

My number keys started to activate other keys when pressed, for example "`1" I only hit the 1 key but the accent key pressed as well. the other numbers activate the special/fn keys above them. hitting the special/ fn keys also activates the numbers below them, although not if I actually hold the fn key. This happened two days ago, then my keyboard quit working entirely, then I left it off for a while and now the keyboard is working again, but the number keys are still messing up~! (see i didn't type that tilde, it just happened_) or that underscore.......

Anyway, does anyone have any ideas?

Thanks~!
