Keyboard doesnt fully function

Hello,
My HP labtop is only like 5 moths old and recently the keys arent working. The letters qweriopjkhgu as well as backspace, shift, and few others randomly scattered acrossed my keyboard. I was wondering if there was a way to fix it. I didn't spill anything on it it worked fine one minute then the next it was acting like a POS. So im really frustrated PLEASE HELP!
