I have a 7/8 month old unibody macbook. No issues so far besides this..

I haven't used it in a few days, turned it on today to type a paper for my class, and the 7,8,u,i,j,k,m,< and left and right arrow keys are not working. Also, when I first turn the computer on and its fully booted up, I have to tap the space bar because it makes the 'dinging' noise like I'm holding it down. (and if I click into spotlight or anything, it makes a bunch of spaces.. hence I know its the space bar :p)


Any suggestions? Thanks!
