Keyboard issue

Hi,

Recently on my TOSHIBA Satellite Pro C50 I've been experiencing an issue. Bare in mind it was working fine yesterday before I slept but had problems in the morning.

The keyboard is working fine, its the functioning. Most of the keys input a different character with the desired key.

Ex.

When i press "3" it inputs "d3" and when i press d it also inputs the same thing.
When i press "." it inputs ".9" and with "9".

I don't know why its doing this, so i wanted to ask if anyones got some ideas on this?

 

Shut it down and do a cold boot. How is the keyboard?
To troubleshoot hardware versus software, I usually attach a USB keyboard to see if the behavior is the same or different.
