Acer Aspire 421-E1 Keyboard Not working

[LinkGaming]

I have an Acer Aspire 421-E1, suddenly one night a few key stopped working and the keys started malfunctioning like when I pressed "L", "3" would show up, thinking of it as a minor problem I shut it down. The next morning when I booted the pc, NO KEYS WERE WORKING.

Please Help, I feel I have tried everything, and am determined to repair without wasting money.

p.s
I am running Windows 8, and have tried a system restore to it's factory settings. NO WORK

How did you do a system restore if the keybd doesnt work for you to navigate thru the restore process?

I see plenty of replacements on amazon so you shouldn't have a problem getting a new one if its not still under warranty.
