Keyboard Barely-not Working Toshiba Satellite?

Toshiba Satellite L775D-S7226 (1 month old) Laptop. Standard PS/2 Keyboard. Mouse working properly. Windows 7 x64 based PC.
Now to the problem….. One day I was using ooVoo chatting to a friend and tried to type in GameRanger and my keyboard suddenly started spamming like hell. Many keys were totally not working and some were falsing entering. For example”k” would show up on screen as “ui”. So I used on-screen keyboard and used malwarebytes. NO VIRUSES. Used AVG NO VIRUSES. Used Norton NO VIRUSES. So I did a system restore same deal. Heres where this REALLY becomes dangerous……. Keyboard doesn’t work on start up screen…..USB plug in keyboards don’t work…. I mean im in desperation. If all your gonna say is ” warranty ” please don’t comment. This problem obviously requires real experts. Step By Step Please.
