Samsung keyboard driver issues?

I have a Samsung NP-R467 laptop (Windows 7 32bit).

when I press the "S" key it outputs "s\"
when I press the "Esc" key it outputs (Esc + F1)

I have tried a USB keyboard, after plugging it in, drivers were installed, computer restarted, and the USB keyboard worked without any problems
I tried the laptop keyboard in BIOS and it seemed to still have the problem
I tried the on-screen key board, no problems
the key board is not dirty
I went to Device Manager > Keyboards > Standard PS/2 Keyboard
I uninstalled drivers, restarted, let windows do it's driver thing, restarted again and still had the same problem

Samsung's website doesn't have any keyboard drivers that I could find
