Numbers and letters

Hello,

So some of the numbers and letters are messing up. If I press 4, r4 appears on my screen. This also happens if I press r. It occurs with a few other combos as well such as o and 0. Something was wrong and the computer crashed and deleted some of the boot up info. I was just able to creat a restore hard drive from a second laptop (same brand and model laptop as this one) and restored it to factory defaults. I've set the reagon info and everything that's right. How do I fix this???
