'eight' and 'nine' keys not responding

This wouldn't be such a big issue if all my passwords didn't contain numbers. I can't even update my adobe software for my organic chemistry homework because of the admin lock I have on my macbook requiring a password!

I bought this macbook in 200nine. It is the 13 inch white macbook with snowleopard.

My keyboard is clean and I tried restarting the laptop with no success.

Help!?
