broken keyboard

So recently my macbook keyboard has been acting funny.
One moment all the number keys and the keys below it werent' functioning properly. SO, if i typed "1" the result would be "1q" or if i typed "er" the result would be "e3r4" so basically the number keys and the ones below it combine. i tried to restart my computer and the problem disappeared, but then it came back again. then all of a sudden it disappeared again and im scared it's going to come back again. any thoughts on why this is happening? note there haven't been any major liquid spills that could damage the keys and even if there were it wouldn't explain why the problem comes and goes randomly.
please help!

I had the same problem for a while. It was really random and it didn't happen often. Every time it happened, I just assumed I over fingered something. Then...my keyboard burned out. I'd get it checked out dude.
