Toshiba Satelline M30 keyboard problem

[paramnirvana]

Hi All,
I started having problem with keyboard. It seems that "V" key has gone crazy. At random times V key get pressed and it keep on inputting V in any application I use. Normally all keys work fine even V key works fine. I have checked for all viruses etc but problem persists.

Any help?

cheers
