On Acer Laptop Keys change Characters

[Funky]

I'm running win7
Machine is an Acer Aspire.
    For no reason My keyboard will develop one key (shift, enter or what ever )
It will create it's own character. Not happening right now (go figure) or I'd show it.
It's a real pain in the chat room because hopebot says you have strike one because it's
a different language. Any help would be appriciated TIA

Have you tried using a USB keyboard to see if it happens as well with another keyboard? The keypad on the laptop may be flawed causing this problem. Testing to see if the problem goes away with a USB keyboard attached when typing on USB keyboard would show whether its an issue with system or keypad of the laptop.
